Definitions
- the invention relates to a method for applying flat strapping bands made of a plastic or metal material to packages by means of a strapping device according to the features of patent claims 1 and 7 and strapping devices for carrying out the method according to patent claims 14 and 20.
- Strapping devices for strapping objects count in different versions of the prior art.
- the basic principle of strapping is based on positioning a strapping head on a package to be strapped, feeding a strapping band around the package, tensioning the strapping band, and joining its ends within the closure head.
- the overlapping ends of the prestressed strapping band become cohesively or positively with each other connected.
- the removed from a supply roll strapping is separated and the closure head lifted from the package.
- Strapping is subject to extreme loads, in particular dynamic loads which occur during the transport of the packages can become so great that the strapping tapes break.
- rod or tube-like metal products are bundled by strapping. When such bundles are transported by means of a crane, deflection forces occur forcibly outside the points of application of the stop means, which in turn leads to displacement of the bars or tubes with one another.
- the strapping bands must absorb the resulting loads. Theoretically, it is possible to provide a larger number of strapping bands to prevent such displacements.
- tube bundles and other rod-like products are so-called rigid packages that have a very limited flexibility.
- the invention is based on the object, a method and an apparatus for bypassing or flipping flat strapping of a plastic or metal material, in particular steel, to show packages that very much because of their high weight, their volume or their critical shape put high demands on the transport protection created by strapping.
- the device according to the invention is based on the basic idea of double or multiple strapping, wherein the beginning of the band of the strapping belt used is guided not only once but several times around the package before being connected to the band end.
- Another aspect is that it is hardly possible in practice to strap packages in such a way that both strapping belts are pretensioned with exactly the same tensile force. The reason is that when creating a first Einzelumreifung the package is compressed and biased. This first strap loop absorbs the entire bias. Although a second belt loop in the form of a single strapping lying directly next to the first belt loop can likewise be pretensioned with a preset tensile force, this results in a, albeit slight, relief of the first belt loop. This is not a uniform burden The strapping more given, with the result that in a Zerr devisprobe one of the strapping earlier failed than the other.
- a decisive influence on the load bearing capacity has the higher elasticity of the multiple strapping due to the greater strip length and the resulting ability to absorb shock loads better.
- the elasticity of a multiple strapping increases linearly with the number of strapping.
- a significant advantage of the invention is that, for the application of multiple strapping, standard strapping bands of metal, i. usually made of steel, or plastic can be used. Although twice the length of strapping must be used for a double strapping, only one closure is necessary, so that with a single closure head a double or multiple strapping can be applied faster than several individual strapping.
- a strapping device in the context of the invention may be a stationarily installed, stationary strapping device, to which the packages are fed, or may be designed as a movably designed device, which moves over a Stabbund. In both cases, the strapping or sealing head is displaceable within predetermined limits relative to the package.
- the methods described below are carried out with the aid of stationary or quasi-stationary strapping devices.
- the automation of the strapping process in a stationary or quasi-stationary strapping device is technically relatively complicated, since the strapping crosses once in a double strapping.
- the method according to claim 1 is as follows:
- the package to be strapped is brought into a strapping position of the strapping device and a closure head is brought into a starting position.
- the closure head feeds the strap, which it removes from a supply roll, to a gripping unit. Between the supply roll and the closure head suitable supply means are provided.
- the gripping unit clamps the beginning of the tape and guides it several times, in particular twice around the package to be strapped. At the same time strapping is tracked by the closure head. After at least two tape loops were applied, the beginning of the tape is fed back to the closure head and held there. In the closure head, the strapping is tensioned by pulling back into the closure head to a preset tensile force. In known In this way, the beginning of the strip inside the closure head is connected to the end of the withdrawn strapping band. The end of the strapping band connected to the supply roll is severed. Subsequently, the closure head is removed from the package again, so that the package can either be removed from the strapping device or positioned so that a further strapping of the package can take place.
- the inventive method it is possible with the inventive method to perform strapping with more than two belt loops. Preferably, however, they are double strapping, i. Strapping with two strap loops.
- the gripping unit is arranged on a guide ring surrounding the package, wherein the guide ring is rotated with the gripping unit to the gripping unit with the clamped beginning of the tape to move around the package.
- the guide ring is fixedly mounted and the gripping unit is moved to the fixed guide ring. In this case, however, the gripping unit would have to be provided with a corresponding drive and a power supply. It is considered easier to turn the guide ring completely, since in this case a power supply to the gripping unit can be omitted.
- a piston-cylinder unit in particular a pneumatic or hydraulic cylinder can be provided for this purpose, which actuates the mechanically acting clamping unit.
- the clamping force is preferably from a Spring force applied, which presses a jaw against the strapping.
- the gripping unit does not collide with the closure head when driving around the package. Therefore, it is necessary to shift the closure head out of the movement path of the gripping unit. This can be done either by the fact that the closure head is moved or the guide ring is displaced when the gripping unit passes through the closure head. If, however, the gripping unit has to transfer the beginning of the strip to the closure head again, the closure head is to be displaced into the movement path of the gripping unit so that the beginning of the strip can be introduced into the band inlet side of the closure head.
- a transport device is arranged between the band inlet side of the closure head and the gripping unit, which transports the strapping band into the closure head after releasing the clamping of the gripping unit.
- This transport device is in a preferred embodiment, a transport roller which presses on a flat side of the belt of the strapping and as well as the closure head in the movement path of the gripping unit is displaced or out of the movement path is displaced when the gripping unit in the application of the first strapping the position the transport device happens.
- suitable guideways may be provided to bring the beginning of the tape in the closure head accurately.
- the strip beginning of the strapping band is to be held in the gripping unit by clamping. This can be done by pressure on its flat sides as well as by clamping the long sides.
- the clamping over the longitudinal edges has the advantage that the strapping can be easily pulled out of the gripper unit when loosening the clamp, which is not readily possible with a clamping on the flat sides.
- the clamping over the longitudinal edges requires that the strapping band not twisted or slip off of the jaws provided in the gripping unit.
- the strapping should be performed arcuate within the gripping unit, so that this arcuate portion is clamped.
- the strapping band can not buckle.
- Of the side of the band end arranged jaws needs only a jaw to be arranged to be movable.
- the movable jaw opposite jaw serves only as an abutment.
- the abutment can be referred to as a jaw.
- the technical problem to be solved in this context is the design of the tape guide channels, which inevitably have to have a crossing point on a side opposite the closure head side.
- a first band guide channel is provided which surrounds the package and a second band guide channel, which connects to the first channel and also surrounds the package.
- additional tape guide channels can be provided to make not only double but triple or quad strapping.
- the technical complexity of triple or quad strapping is very high, since there must be opportunities at the intersection of each band guide channels to open the respective inner band guide channels when the closure head spans the strapping.
- the core of the method according to claim 7, therefore, is that the closure head opposite intersection of the band guide channels is released.
- the inner, closer to the package strip guide channel is executed divided, wherein at least one of its sections is moved out of the crossing point.
- the crossing point is released, the strapping band can be pulled into the closure head and thus tensioned.
- spring-loaded holding means are provided for the strapping, which open automatically overcoming the spring force and release the strapping, so that it can get to the package to the plant.
- both tape guide channels so that they are opened at the intersection, for example, if rod-shaped packages are to be introduced in a sense not in the axial direction of the openings formed by the tape guide channels, but in the radial direction, so to speak, transversely to the tape guide channels in the strapping.
- rod-shaped packages are to be introduced in a sense not in the axial direction of the openings formed by the tape guide channels, but in the radial direction, so to speak, transversely to the tape guide channels in the strapping.
- an inner and at least one further, outer band guide channel is provided
- the alternative according to claim 9 is to rigidly form the band guide channels and to connect them at the point of intersection.
- an intersection is provided.
- the essence, however, is that not all the band channel has to be moved out of the intersection, but only one slider separating the inner band channel from the outer band channel has to be opened to receive both the inner band and the outer band from the respective band channels and pull out the tape guide channels.
- Such a slider has the advantage that it is a much smaller moving component, as in a whole band guide channel. Therefore even smaller drive units are required.
- the construction is more compact.
- the slider has two functions during the running in of the band: on the one hand, it is the wall of the outer band channel but at the same time also the boundary of the inner band channel.
- the slider is even configured in a U-shape such that it forms three walls of the inner band channel within the crossing region like a fork.
- the strapping enters after entering the first band guide channel in the second band guide channel, via a bypass channel which extends along the closure head.
- the bypass channel is connected to the end of the first tape guide channel and the beginning of the second tape guide channel.
- This bypass channel is preferably positioned as close as possible to the tape inlet and outlet channel of the closure head, so that the distance of the belt loops is minimized. In this way it is ensured that the strapping does not loosen by lateral displacement of one or both of the strap loops, with the result that the bias of the strapping decreases.
- bypass channel is opened after the application of the belt loops and the belt loop is displaced from the bypass channel in the direction of the tape inlet and outlet channel of the closure head. This measure can be done with a reduced band loop before tightening the strapping. Regardless of this, it is considered expedient if the displaced belt loop is prevented from displacing out of this position into the bypass channel after being displaced into the region of the belt inlet and outlet channel by at least one blocking element.
- the blocking element is preferably a pawl which is mechanically coupled to a pusher element which is used to displace the second band loop into the band inlet and outlet channel.
- the strapping device according to claim 14 is intended to carry out the method according to claim 1. It is an automated device in which the complete strapping process is controlled by a control unit.
- the strapping device is for this purpose provided with corresponding actuators and sensors which are connected to the control unit.
- the strapping device comprises in this embodiment, a gripping unit, which has means to grab a pushed out of the closure head strip beginning and perform several times around the package and finally feed the tape back to the closure head.
- the gripping unit is arranged on a displaceable in a rotational movement about the package guide ring.
- the closure head can be displaced out of the movement path of the gripping unit in order not to come into contact with the gripping unit after the application of the first belt loop. A displacement of the gripping unit is also possible.
- the gripping unit is located in front of the band inlet side of the closure head.
- a transport device can be introduced between the closure head and the gripping unit in order to transport the beginning of the strip into the band inlet side of the closure head.
- the tape end is not guided by a gripping unit, but by tape guide channels, which surround the package to be strapped twice.
- tape guide channels which surround the package to be strapped twice.
- the inner band guide channel adjacent to the package is divided in a first embodiment so that at least one of its sections can be moved out of the crossing region, in particular swung out.
- moving out or swinging out of the sections of the packaging tape is freed from surrounding parts and can be pulled out of the band guide channel until it rests on the package.
- FIG. 1 shows a first side view of a first embodiment of a strapping device 1.
- the strapping device 1 comprises a frame 2 with a movable in height boom 3, on which a closure head 4 is arranged.
- the closure head 4 serves a in FIG. 8 illustrated strapping 17 output, which is a package. 5 to be led around.
- the package 5 is configured hexagonal in cross-section. For example, it is a bundle of rods or tubes. The smaller of the two hexagons shown should make it clear that the package 5 can have different sizes.
- the closure head 4 is located above the package 5. It is positioned so that the closure attached by the closure head 4 is always located centrally on the top of the package 5. For this purpose, the closure head 4 can be displaced in not horizontally positioned packages 5 in a manner not shown in the horizontal direction.
- the strapping device 1 further comprises a guide ring 6 which surrounds the package 5 and is rotatably mounted about its longitudinal axis L. With the guide ring 6, a gripping unit 7 is fixedly connected. When the guide ring 6 is set in a rotational movement, the gripping unit 7 also rotates about the longitudinal axis L and thus around the package 5.
- the gripping unit 7 is intended to grab a issued by the closure head 4 strapping 17 at its beginning of the tape 31 and to fix it by clamping.
- the gripping unit 7 is provided with a jaw 8.
- the jaw 8 would act on the wider flat sides of the strap 17.
- the clamping jaw 8 can also act on a narrow side of the strip beginning 31.
- FIGS. 18 and 19 show a perspective view of a gripping unit 7 in two different positions.
- the gripping unit 7 comprises a supporting jaw 42 and a clamping jaw 43 which is displaceable in the direction of the arrow P8 in the direction of the supporting jaw 42.
- the support jaw 42 serves as an abutment for the clamping jaw 43. Between the support jaw 42 and the clamping jaw 43, the beginning of the strip 31 of the strapping band 17 is clamped, specifically over the narrow longitudinal edges of the strapping band 17. Thus, the strapping band 17 does not buckle in this type of fixation, the jaw 43 and the support jaw 42 are arcuately curved in their course.
- the jaw 43 and the jaw 42 are configured in a substantially L-shaped cross section so that the tape top and the tape bottom are guided inside the gripping unit 7.
- the clamping jaw 43 is pressed under the influence of a spring force in the direction of the support jaw 42.
- the closure head 4 is pivoted back and the gripping unit 7 in the in FIG. 4 stopped position shown.
- the gripping unit 7 is now located on the rear side of the closure head 4.
- the strapping device 1 uses a transport device 9 in the form of a transport roller, which transports the strip beginning after the clamping of the gripping unit 7 via an arcuate insertion ramp 10 in a Bandein- and outlet channel on the tape inlet side 11 of the closure head 4.
- the jaw 43 all or at least so far open that the band has enough space for the transport described above.
- the tape end is clamped by the closure head 4 in a known manner and excess strapping 17 is withdrawn through the tape outlet to tension the strapping 17 with a predetermined tensile force.
- the closure head 4 is located very close to the surface of the package 5.
- the tensioned strapping 17 is connected to the strip beginning 31 ( FIG. 8 ).
- strapping bands 17 made of steel this is done for example by welding. Of course, positive connections are possible by direct compression or using closure sleeves.
- the still connected to the supply roll end of the strap 17 is separated.
- the closure head 4 is lifted from the package 5 and the package 5 can be removed from the strapping device 1. Subsequently, the gripping unit 7 moves back to the starting position, as in FIG. 1 is shown.
- closure head 4 can be pivoted again in the direction of the arrow P3, as it FIG. 5 shows, so that the closure head 4 is returned to the starting position with the same direction of rotation.
- FIGS. 6 and 7 show a further embodiment of a strapping device 12, which operates on a different principle than that of the FIGS. 1 to 5 ,
- the strapping device 12 according to FIG. 6 does not require a gripping unit 7 in order to guide the beginning of the strip 31. It has for this purpose band guide channels 13, 14. In the present case, a double strapping is to be created. Therefore, two tape guide channels 13, 14 are provided. In a double strapping, as in FIG. 8 is shown, there is inevitably a crossing point K, in which the belt loops 15, 16 of the strapping 17 intersect. When using tape guide channels 13, 14, it is unavoidable during the application of the belt loops 15, 16 that one of the belt guide channels 13, 14 is closer to the package 5, than the other. When the strapping band 17 is tensioned, it must be ensured that the band loop 15 extending at the intersection point K does not collide with the inner band guide channel 13.
- FIG. 6 is provided to pivot the inner band guide channel 13 to release the intersection point K.
- the inner band guide channel 13 is shown in two positions. Once in the closed position and once in the open position in which the lower ends of the inner band guide channel 13 are spaced from each other. After applying the double strapping the outwardly pivoted portions 18, 19 of the inner band guide channel 13 are brought together again, so that the next strapping process can be performed.
- FIG. 7 illustrates once again, the intersecting course of the two band guide channels 13, 14 and their connection to the closure head. 4
- the inner band guide channel 13 is in the embodiment of a strapping device 20 according to FIG. 12 provided to use an intersection part 21, whose operation is described below with reference to FIG. 9 is explained.
- none of the band guide channels must be pivoted. They are executed in a sense rigid and connected to each other via the intersection part 21.
- the crossing part 21 has two superimposed band channels, one of which, the inner, the package 5 closer band channel 22 and one of the package 5 further away outer band channel 23 is.
- the outer band channel 23 has a greater depth than the inner band channel 22.
- the inner band channel 22 crosses the outer band channel 23 and is of this in the region of the crossing point K via a displaceable in the direction of arrow P4 slide 25 of the outer band channel 23 separately.
- the slider 25 is in the darg Congressen position in a closed position and covers by its U-shaped configuration with its lower leg 34, the inner band channel 22 and with its upper leg of the outer band channel 23 in the image plane upwards from.
- An insertion bevel 24 ensures that in the direction of the arrow P4 entering the crossing part 21 strapping 17 passes in the image plane below the slide 25.
- the strapping 17 passes from the direction of the arrow P5 in the inner band channel 22 and extends between the rear leg 34 and the upper leg 35 of the slider 25.
- the slider 25 is retracted in the direction of the arrow P3, so that the band channels 23, 24 are released. As a result, this can also emerge from the outer band channel 23 when tensioning the strapping band 17.
- the slider 25 is again moved into the illustrated closure position, so that a further strapping process can take place.
- the two belt loops 15, 16 should run as close together as possible. In other words, the distance A ( FIG. 8 ) as small as possible. This assumes that the tape guide channels 26, 27, as they are in FIG. 10 can be seen as closely as possible with each other. However, this would also mean that the crossing part 21 has to be made longer if the belt loops 15, 16 at the crossing point K are at a very acute angle to each other. On the other hand, the belt loops 15, 16 in their in the FIG. 8 shown upper region, ie in the region of the closure head 4 due to the parallel guide at a relatively small distance from each other.
- band guide channels 26, 27 are not only arcuately curved, but slightly wound in the direction of their longitudinal extent, that are twisted about their longitudinal axis. It is in the band guide channels 26, 27 therefore geometrically complicated components. Therefore, it is expedient for manufacturing reasons, the band guide channels 15, 16 to build multiple parts, wherein at least the area between the closure head 4 and the Junction 21 is divided into two lengths, which are connected to each other in the middle.
- bypass channel 28 extending parallel to the closure head 4 region of the belt loops 15, 16 in the direction of the belt loop in the belt inlet and outlet channel 29 of the closure head 4th to relocate.
- FIG. 11 in the upper half a Bandein- and outlet channel 29, which is located within the closure head 4, not shown.
- this Bandein- and outlet channel 29 is located with reference to FIG. 8 a partial section of a first belt loop 15.
- Parallel to the belt inlet and outlet channel 29 extends the bypass channel 28, in which the second belt loop 16 is located.
- the band inlet and outlet channel 29 is spatially separated from the bypass channel 28, so that the in FIG. 8 shown end of tape 31 can easily pass through the bypass channel 28 when creating the belt loop 16.
- the bypass channel 16 is partially bounded on its narrow side facing away from the band inlet and outlet channel 29 by a pusher element 32.
- the lateral displacement of the belt loop 16 from the bypass channel 28 takes place before the strapping band 17 is tensioned.
- the blocking element 33 is preferably a pawl which is coupled to the pusher element 32.
- the thrust element 32 shown in greatly simplified form is preferably configured fork-shaped and encompasses both the top and bottom of the belt loop 16 to be displaced in order to guide it exactly even during the displacement.
- FIGS. 14 and 15 show in side view a much simplified closure head 30, in particular, the area of the band guide channels is of interest.
- FIG. 14 or in the enlarged view of FIG. 16 It can be seen that a partial section of the first belt loop 15 is located in a belt inlet and outlet channel 29, while the second belt loop 16 is located in the closed bypass channel 28.
- the bypass channel 28 is constructed in two parts and comprises a fixed upper part 36 and a pivoting lower part 37, which via a pivot mechanism 38 to a lying above the upper part 36 pivot point S in the in FIG. 15 or 17 shown position is displaced.
- the pivot point S is located at a relatively large distance from the bypass channel 28, so that the lower part 37 does not deflect too far down and thereby collides with the package to be strapped.
- FIG. 17 shows the position of the belt loop 16 after it has been pushed out of the bypass channel 28 out. It is located at a parallel distance from the belt loop 15 in the belt inlet and outlet channel 29. The distance is possible not greater than 3 mm. So that the belt loop 16 does not jam when pushed out of the bypass channel 28, the side walls of the bypass channel 28 may be bevelled.
- corresponding inclined surfaces 39, 40 to recognize both the upper part 36 and the lower part 37.
- the pivot mechanism 38 comprises in this embodiment, a piston-cylinder unit 41, which is in particular a pneumatic cylinder.
- the entire strapping process is fully automatic.
- actuators, sensors and the necessary control means are provided in a manner not shown.

Abstract
Description
Die Erfindung betrifft einerseits Verfahren zum Anlegen von flachen Umreifungsbändern aus einem Kunststoff- oder Metallwerkstoff um Packstücke mittels einer Umreifungsvorrichtung gemäß den Merkmalen der Patentansprüche 1 und 7 sowie Umreifungsvorrichtungen zur Durchführung des Verfahrens gemäß den Patentansprüchen 14 und 20.On the one hand, the invention relates to a method for applying flat strapping bands made of a plastic or metal material to packages by means of a strapping device according to the features of
Umreifungsvorrichtungen zum Umreifen von Objekten, insbesondere von Packstücken zählen in unterschiedlichen Ausführungen zum Stand der Technik. Das grundlegende Prinzip des Umreifens basiert darauf, einen Umreifungs- oder Verschlusskopf an einem zu umreifenden Packstück zu positionieren, ein Umreifungsband um das Packstück herum zuführen, das Umreifungsband zu spannen und seine Enden innerhalb des Verschlusskopfes miteinander zu verbinden. Die sich überlappenden Enden des vorgespannten Umreifungsbands werden stoffschlüssig oder formschlüssig miteinander verbunden. Das von einer Vorratsrolle entnommene Umreifungsband wird abgetrennt und der Verschlusskopf vom Packstück abgehoben. Diese Arbeitsschritte erfolgen automatisiert.Strapping devices for strapping objects, in particular packages count in different versions of the prior art. The basic principle of strapping is based on positioning a strapping head on a package to be strapped, feeding a strapping band around the package, tensioning the strapping band, and joining its ends within the closure head. The overlapping ends of the prestressed strapping band become cohesively or positively with each other connected. The removed from a supply roll strapping is separated and the closure head lifted from the package. These steps are automated.
Umreifungen unterliegen extremen Belastungen, wobei insbesondere dynamische Belastungen, die während des Transports der Packstücke auftreten, so groß werden können, dass die Umreifungsbänder reißen. Beispielsweise werden stab- oder rohrähnliche Metallprodukte durch Umreifungsbänder gebündelt. Wenn solche Bunde mittels eines Krans transportiert werden, kommt es außerhalb der Kraftangriffspunkte der Anschlagmittel zwangsweise zu Durchbiegungen, was wiederum zum Verschieben der Stäbe oder Rohre untereinander führt. Die Umreifungsbänder müssen die daraus resultierenden Belastungen aufnehmen. Theoretisch ist es möglich, eine größere Anzahl von Umreifungsbändern vorzusehen, um derartige Verschiebungen zu verhindern. Allerdings handelt es gerade bei Rohrbunden und anderen stabähnlichen Produkten um so genannte starre Packstücke, die eine sehr begrenzte Nachgiebigkeit haben. Da die Umreifungsbänder insofern stark vorgespannt werden müssen, um Verschiebungen innerhalb des Bündels zu vermeiden, können zusätzliche stoßartige Belastungen, wie beim Anheben oder Absenken des Bündels mittels eines Krans unter Durchbiegung des Stangenbündels, zu Spannungsspitzen innerhalb der Umreifungsbänder führen, die über der Belastungsgrenze der Umreifungsbänder liegen. Ähnlich große Belastungen treten beim Verfrachten der Bunde auf.Strapping is subject to extreme loads, in particular dynamic loads which occur during the transport of the packages can become so great that the strapping tapes break. For example, rod or tube-like metal products are bundled by strapping. When such bundles are transported by means of a crane, deflection forces occur forcibly outside the points of application of the stop means, which in turn leads to displacement of the bars or tubes with one another. The strapping bands must absorb the resulting loads. Theoretically, it is possible to provide a larger number of strapping bands to prevent such displacements. However, tube bundles and other rod-like products are so-called rigid packages that have a very limited flexibility. Since the strapping bands must be strongly biased in order to avoid shifts within the bundle, additional shock loads, such as lifting or lowering the bundle by means of a crane under flexure of the bundle, can lead to stress peaks within the strapping bands that exceed the load limit of the straps lie. Similarly large loads occur when shipping the bundles.
Hiervon ausgehend liegt der Erfindung die Aufgabe zu Grunde, ein Verfahren sowie eine Vorrichtung zum Umführen oder Umlegen von flachen Umreifungsbändern aus einem Kunststoff- oder Metallwerkstoff, insbesondere aus Stahl, um Packstücke aufzuzeigen, die wegen ihres hohen Gewichts, ihres Volumens oder ihrer kritischen Form sehr hohe Anforderungen an die durch Umreifen angelegte Transportsicherung stellen.On this basis, the invention is based on the object, a method and an apparatus for bypassing or flipping flat strapping of a plastic or metal material, in particular steel, to show packages that very much because of their high weight, their volume or their critical shape put high demands on the transport protection created by strapping.
Diese Aufgabe wird durch die Verfahren gemäß der Patentansprüche 1 und 7 bzw. die Verrichtungen zur Durchführung des Verfahrens gemäß der Patentansprüche 14 und 20 gelöst.This object is achieved by the methods according to the
Die erfindungsgemäße Vorrichtung basiert auf dem Grundgedanken, der Doppel- oder Mehrfachumreifung, wobei der Bandanfang des eingesetzten Umreifungsbandes vor dem Verbinden mit dem Bandende nicht nur einmal sondern mehrmals um das Packstück herum geführt wird.The device according to the invention is based on the basic idea of double or multiple strapping, wherein the beginning of the band of the strapping belt used is guided not only once but several times around the package before being connected to the band end.
Man könnte vermuten, dass bei einer Doppel- oder Mehrfachumreifung im Sinne der Erfindung keine höheren Belastungen aufgenommen werden können, als bei zwei dicht nebeneinander liegenden Einzelumreifungen. Versuche haben jedoch bestätigt, dass die Lastaufnahmekapazität bei Doppelt-oder Mehrfachumreifungen gegenüber der gleichen Anzahl von Einfachumreifungen signifikant erhöht ist. Der Grund ist, dass sich die Belastungen bei zwei oder mehr Bandschlaufen umfassenden Umreifungen auf alle Bandschlaufen gleichmäßig verteilen. Bei zwei parallel zueinander angelegten Einfachumreifungen bietet sich dieser Vorteil nicht, da keine Ausgleichsmöglichkeit zwischen den beiden Bandschlaufen besteht. Die Festigkeit von zwei einzeln angelegten Umreifungen ist nur dann mit der einer Doppelschlaufe zu vergleichen, wenn die Belastung so einwirken kann, dass beide Einzelumreifungen absolut gleich belastet werden. Diese Art der Belastung ist theoretischer Natur und kommt in der Praxis nicht vor.One might suspect that in a double or multiple strapping in the context of the invention, no higher loads can be absorbed, as in two closely juxtaposed Einzelumreifungen. However, tests have confirmed that the load bearing capacity is significantly increased in double or multiple strapping over the same number of single strappings. The reason is that the strains are evenly distributed on all belt loops with two or more strap loops. With two parallel straightening single strapping this advantage does not offer, since there is no compensation between the two belt loops. The strength of two individually applied strapping can only be compared with that of a double loop, if the load can act in such a way that both individual strappings are loaded absolutely equally. This type of stress is theoretical and does not occur in practice.
Ein weiterer Aspekt ist, dass es in der Praxis kaum möglich ist, Packstücke so zu umreifen, dass beide Umreifungsbänder mit exakt der gleichen Zugkraft vorgespannt werden. Der Grund ist, dass beim Anlegen einer ersten Einzelumreifung das Packstück komprimiert und vorgespannt wird. Diese erste Bandschlaufe nimmt die gesamte Vorspannung auf. Eine unmittelbar neben der ersten Bandschlaufe liegende zweite Bandschlaufe in Form einer Einzelumreifung kann zwar ebenfalls mit einer voreingestellten Zugkraft vorgespannt werden, diese führt jedoch zu einer, wenn auch geringfügigen, Entlastung der ersten Bandschlaufe. Damit ist keine gleichmäßige Belastung der Umreifungsbänder mehr gegeben, mit der Folge, dass bei einer Zerreißprobe eines der Umreifungsbänder früher versagt als das andere.Another aspect is that it is hardly possible in practice to strap packages in such a way that both strapping belts are pretensioned with exactly the same tensile force. The reason is that when creating a first Einzelumreifung the package is compressed and biased. This first strap loop absorbs the entire bias. Although a second belt loop in the form of a single strapping lying directly next to the first belt loop can likewise be pretensioned with a preset tensile force, this results in a, albeit slight, relief of the first belt loop. This is not a uniform burden The strapping more given, with the result that in a Zerreißprobe one of the strapping earlier failed than the other.
Es wurden Versuche mit einem Stahlband der Abmessungen 19 mm Breite * 0,8 mm Dicke und einer Festigkeit von 15.483 N gemacht. Bei einer Einfachschlaufe, deren Bandenden über zwei Schweißpunkte miteinander verbunden wurden, ergab sich der Bandriss bei einer von einer Ausdehnung des umreiften Testpackstücks ausgehenden Belastung von 29.527 N und einer Dehnlänge von 13 mm. Bei dem gleichen Stahlband, das zu einer Doppelschlaufe gelegt wurde, erfolgte der Bandriss erst bei etwa 58.000 N und einer Dehnlänge von 19 mm. Bei einem Stahlband der Abmessungen 19 mm Breite * 1,0 mm Dicke war der Unterschied sogar noch größer. Das verwendete Band hatte eine Festigkeit von 19.598 N. Während eine mit zwei Schweißpunkten verschlossene Einfachschlaufe bei einer Belastung von 35.807 Nm gerissen ist und zwei nebeneinander liegende Einzelbänder, die ebenfalls über zwei Schweißpunkte verschlossen worden sind, eine Belastung von 56.941 N aushielten, war eine Doppelschlaufe, deren Enden ebenfalls mit zwei Schweißpunkten verschlossen waren, mit einer Belastung von 71.580 N bis zum Bandriss belastbar. Der Bandriss erfolgte dabei niemals im Bereich des Verschlusses, sondern in außerhalb des Verschlusses liegenden Bereichen. Vergleichsversuche, bei denen die Bandenden bzw. der Verschluss nicht oben liegend positioniert war, sondern seitlich, so dass sich das Umreifungsband ausgehend vom Verschluss nach oben und unten erstreckt, haben bestätigt, dass sich auch in diesem Fall fast eine Verdopplung der Reißfestigkeit gegenüber der Einfachumreifung einstellt.Experiments were carried out with a steel strip measuring 19 mm wide * 0.8 mm thick and having a strength of 15,483 N. For a single loop, whose ends were joined by two welds, the band break resulted in a load of 29,527 N and a stretch of 13 mm due to an extension of the strapped test pack. For the same steel strip, which was laid in a double loop, the strip was torn off only at about 58,000 N and a stretching length of 19 mm. For a 19 mm wide * 1.0 mm thick steel strip, the difference was even greater. The tape used had a strength of 19,598 N. While a single loop closed with two welds tore at a load of 35,807 Nm and two adjacent single tapes, which were also closed by two welds, withstood a load of 56,941 N., a double loop was , whose ends were also closed with two welds, loadable with a load of 71,580 N until the band break. The ligament tear never occurred in the area of the closure, but in areas outside the closure. Comparative tests in which the tape ends or the closure was not positioned at the top, but laterally, so that the strapping extends from the closure up and down, have confirmed that in this case almost a doubling of the tensile strength compared to the single strapping established.
Einen entscheidenden Einfluss auf das Lastaufnahmevermögen hat die höhere Elastizität der Mehrfachumreifung auf Grund der größeren Bandlänge und der daraus resultierenden Fähigkeit, Schockbelastungen besser aufzunehmen. Die Elastizität einer Mehrfachumreifung steigt linear mit der Anzahl der Umreifungen an.A decisive influence on the load bearing capacity has the higher elasticity of the multiple strapping due to the greater strip length and the resulting ability to absorb shock loads better. The elasticity of a multiple strapping increases linearly with the number of strapping.
Ein wesentlicher Vorteil der Erfindung ist, dass für das Anlegen der Mehrfachumreifungen genormte Umreifungsbänder aus Metall, d.h. in der Regel aus Stahl, oder auch aus Kunststoff eingesetzt werden können. Zwar muss für eine Doppelumreifung auch die doppelte Länge von Umreifungsband eingesetzt werden, allerdings ist nur ein Verschluss notwendig, so dass mit einem einzigen Verschlusskopf eine Doppel- oder Mehrfachumreifung schneller angelegt werden kann, als mehrere einzelne Umreifungen.A significant advantage of the invention is that, for the application of multiple strapping, standard strapping bands of metal, i. usually made of steel, or plastic can be used. Although twice the length of strapping must be used for a double strapping, only one closure is necessary, so that with a single closure head a double or multiple strapping can be applied faster than several individual strapping.
Eine Umreifungsvorrichtung im Sinne der Erfindung kann eine ortsfest installierte, stationäre Umreifungsvorrichtung sein, der die Packstücke zugeführt werden, oder kann als verfahrbar gestaltete Einrichtung ausgebildet sein, die über ein Stabbund verfährt. In beiden Fällen ist der Umreifungs- bzw. Verschlusskopf in vorbestimmten Grenzen relativ zum Packstück verlagerbar. Die nachfolgend beschriebenen Verfahren werden mit Hilfe von stationären bzw. quasi-stationären Umreifungsvorrichtungen durchgeführt. Die Automatisierung des Umreifungsvorgangs in einer stationären oder quasi-stationären Umreifungsvorrichtung ist technisch relativ aufwendig, da sich das Umreifungsband bei einer Doppelumreifung einmal kreuzt. Das Verfahren gemäß Patentanspruch 1 läuft folgendermaßen ab:A strapping device in the context of the invention may be a stationarily installed, stationary strapping device, to which the packages are fed, or may be designed as a movably designed device, which moves over a Stabbund. In both cases, the strapping or sealing head is displaceable within predetermined limits relative to the package. The methods described below are carried out with the aid of stationary or quasi-stationary strapping devices. The automation of the strapping process in a stationary or quasi-stationary strapping device is technically relatively complicated, since the strapping crosses once in a double strapping. The method according to
Das zu umreifende Packstück wird in eine Umreifungsposition der Umreifungsvorrichtung gebracht und ein Verschlusskopf in eine Ausgangsposition gebracht. Der Verschlusskopf führt das Umreifungsband, das er von einer Vorratsrolle entnimmt, einer Greifeinheit zu. Zwischen der Vorratsrolle und dem Verschlusskopf sind geeignete Zuführmittel vorgesehen.The package to be strapped is brought into a strapping position of the strapping device and a closure head is brought into a starting position. The closure head feeds the strap, which it removes from a supply roll, to a gripping unit. Between the supply roll and the closure head suitable supply means are provided.
Bei dieser ersten Variante klemmt die Greifeinheit den Bandanfang und führt diesen mehrfach, insbesondere zweifach um das zu umreifende Packstück. Gleichzeitig wird Umreifungsband von dem Verschlusskopf nachgeführt. Nachdem wenigstens zwei Bandschlaufen angelegt wurden, wird der Bandanfang wieder dem Verschlusskopf zugeführt und dort gehalten. Im Verschlusskopf wird das Umreifungsband durch zurückziehen in den Verschlusskopf bis zu einer voreingestellten Zugkraft gespannt. In bekannter Weise wird der Bandanfang innerhalb des Verschlusskopfes mit dem Ende des zurückgezogenen Umreifungsbands verbunden. Das mit der Vorratsrolle verbundene Ende des Umreifungsbands wird abgetrennt. Anschließend wird der Verschlusskopf wieder von dem Packstück entfernt, so dass das Packstück entweder aus der Umreifungsvorrichtung entnommen werden kann oder so positioniert wird, dass eine weitere Umreifung des Packstücks erfolgen kann.In this first variant, the gripping unit clamps the beginning of the tape and guides it several times, in particular twice around the package to be strapped. At the same time strapping is tracked by the closure head. After at least two tape loops were applied, the beginning of the tape is fed back to the closure head and held there. In the closure head, the strapping is tensioned by pulling back into the closure head to a preset tensile force. In known In this way, the beginning of the strip inside the closure head is connected to the end of the withdrawn strapping band. The end of the strapping band connected to the supply roll is severed. Subsequently, the closure head is removed from the package again, so that the package can either be removed from the strapping device or positioned so that a further strapping of the package can take place.
Theoretisch ist es mit dem erfindungsgemäßen Verfahren möglich, Umreifungen mit mehr als zwei Bandschlaufen durchzuführen. Bevorzugt handelt es sich jedoch um Doppelumreifungen, d.h. Umreifungen mit zwei Bandschlaufen.Theoretically, it is possible with the inventive method to perform strapping with more than two belt loops. Preferably, however, they are double strapping, i. Strapping with two strap loops.
Bei dem vorbeschriebenen Verfahren wird nur der in der Greifeinheit geklemmte Bandanfang geführt, während das von der Greifeinheit mitgeschleppte Umreifungsband gewissermaßen frei verläuft. Da die Greifeinheit mehr als einmal um das Packstück geführt werden muss, wird es als zweckmäßig angesehen, wenn die Greifeinheit an einem das Packstück umgebenden Führungsring angeordnet ist, wobei der Führungsring mit der Greifeinheit in eine Drehbewegung versetzt wird, um die Greifeinheit mit dem geklemmten Bandanfang um das Packstück herum zu bewegen. Theoretisch ist es auch möglich, dass der Führungsring feststehend montiert ist und die Greifeinheit an dem feststehenden Führungsring verfahren wird. In diesem Fall müsste jedoch die Greifeinheit mit einem entsprechenden Antrieb und einer Energiezuführung vorgesehen werden. Es wird als einfacher angesehen, den Führungsring komplett zu drehen, da in diesem Fall eine Energiezuführung zur Greifeinheit entfallen kann.In the method described above, only the clamped in the gripping unit tape start is performed while the entrained by the gripping unit strapping runs, so to speak, free. Since the gripping unit has to be guided more than once around the package, it is considered appropriate if the gripping unit is arranged on a guide ring surrounding the package, wherein the guide ring is rotated with the gripping unit to the gripping unit with the clamped beginning of the tape to move around the package. Theoretically, it is also possible that the guide ring is fixedly mounted and the gripping unit is moved to the fixed guide ring. In this case, however, the gripping unit would have to be provided with a corresponding drive and a power supply. It is considered easier to turn the guide ring completely, since in this case a power supply to the gripping unit can be omitted.
Es wird nur dann eine Energiezuführung benötigt, wenn das Band geklemmt oder gelöst werden soll. In der Ausgangs- bzw. Endposition der Greifeinheit kann zu diesem Zweck eine Kolben-Zylinder-Einheit, insbesondere ein Pneumatik- oder Hydraulikzylinder vorgesehen sein, der die mechanisch wirkende Klemmeinheit betätigt. Die Klemmkraft wird bevorzugt von einer Federkraft aufgebracht, die eine Klemmbacke gegen das Umreifungsband presst.It is only a power supply needed if the tape is to be clamped or loosened. In the starting or end position of the gripping unit, a piston-cylinder unit, in particular a pneumatic or hydraulic cylinder can be provided for this purpose, which actuates the mechanically acting clamping unit. The clamping force is preferably from a Spring force applied, which presses a jaw against the strapping.
Ein weiterer wesentlicher Aspekt ist, dass die Greifeinheit beim Umfahren des Packstücks nicht mit dem Verschlusskopf kollidiert. Daher ist es erforderlich, den Verschlusskopf aus der Bewegungsbahn der Greifeinheit zu verlagern. Dies kann entweder dadurch erfolgen, dass der Verschlusskopf bewegt wird oder aber der Führungsring verlagert wird, wenn die Greifeinheit den Verschlusskopf passiert. Wenn allerdings die Greifeinheit den Bandanfang an den Verschlusskopf wieder übergeben muss, ist der Verschlusskopf in die Bewegungsbahn der Greifeinheit zu verlagern, so dass der Bandanfang in die Bandeinlaufseite des Verschlusskopfes eingebracht werden kann.Another essential aspect is that the gripping unit does not collide with the closure head when driving around the package. Therefore, it is necessary to shift the closure head out of the movement path of the gripping unit. This can be done either by the fact that the closure head is moved or the guide ring is displaced when the gripping unit passes through the closure head. If, however, the gripping unit has to transfer the beginning of the strip to the closure head again, the closure head is to be displaced into the movement path of the gripping unit so that the beginning of the strip can be introduced into the band inlet side of the closure head.
Für diesen Verfahrensschritt ist zwischen der Bandeinlaufseite des Verschlusskopfes und der Greifeinheit eine Transportvorrichtung angeordnet, welche nach Lösen der Klemmung der Greifeinheit das Umreifungsband in den Verschlusskopf transportiert. Diese Transportvorrichtung ist in bevorzugter Ausgestaltung eine Transportrolle, welche auf eine Flachseite des Bandes des Umreifungsbandes drückt und ebenso wie der Verschlusskopf in die Bewegungsbahn der Greifeinheit verlagerbar ist bzw. aus der Bewegungsbahn heraus verlagerbar ist, wenn die Greifeinheit bei dem Anlegen der ersten Umreifung die Position der Transportvorrichtung passiert. An der Bandeinlaufseite des Verschlusskopfes bzw. an der Transportvorrichtung können geeignete Führungsbahnen vorgesehen sein, um den Bandanfang in den Verschlusskopf zielgenau einzubringen.For this method step, a transport device is arranged between the band inlet side of the closure head and the gripping unit, which transports the strapping band into the closure head after releasing the clamping of the gripping unit. This transport device is in a preferred embodiment, a transport roller which presses on a flat side of the belt of the strapping and as well as the closure head in the movement path of the gripping unit is displaced or out of the movement path is displaced when the gripping unit in the application of the first strapping the position the transport device happens. At the band inlet side of the closure head or on the transport device suitable guideways may be provided to bring the beginning of the tape in the closure head accurately.
Der Bandanfang des Umreifungsbands soll in der Greifeinheit durch Klemmung gehalten werden. Dies kann sowohl durch Druck auf seine Flachseiten als auch durch Klemmung der Längsseiten erfolgen. Die Klemmung über die Längsflanken hat den Vorteil, dass das Umreifungsband beim Lösen der Klemmung leicht aus der Greifeinheit herausgezogen werden kann, was bei einer Klemmung über die Flachseiten nicht ohne Weiteres möglich ist. Die Klemmung über die Längsflanken setzt voraus, dass sich das Umreifungsband nicht verwindet oder von den in der Greifeinheit vorgesehenen Klemmbacken abrutscht. Hierzu sollte das Umreifungsband innerhalb der Greifeinheit bogenförmig geführt werden, so dass dieser bogenförmige Abschnitt geklemmt wird. Dadurch kann das Umreifungsband nicht wegknicken. Von den seitlich des Bandendes angeordneten Klemmbacken braucht nur eine Klemmbacke beweglich angeordnet zu sein. Die der beweglichen Klemmbacke gegenüberliegende Klemmbacke dient in diesem Fall lediglich als Widerlager. Das Widerlager kann als Stützbacke bezeichnet werden.The strip beginning of the strapping band is to be held in the gripping unit by clamping. This can be done by pressure on its flat sides as well as by clamping the long sides. The clamping over the longitudinal edges has the advantage that the strapping can be easily pulled out of the gripper unit when loosening the clamp, which is not readily possible with a clamping on the flat sides. The clamping over the longitudinal edges requires that the strapping band not twisted or slip off of the jaws provided in the gripping unit. For this purpose, the strapping should be performed arcuate within the gripping unit, so that this arcuate portion is clamped. As a result, the strapping band can not buckle. Of the side of the band end arranged jaws needs only a jaw to be arranged to be movable. The movable jaw opposite jaw in this case serves only as an abutment. The abutment can be referred to as a jaw.
Alternativ zu der freien Bandführung durch eine Greifeinheit, die nur den Bandanfang hält, wird im Rahmen der Erfindung ein Verfahren gemäß Patentanspruch 7 vorgeschlagen, bei welchem der Bandanfang durch Bandführungskanäle geschoben wird, so dass das Umreifungsband über die gesamte Länge geführt wird.As an alternative to the free tape guide by a gripping unit, which holds only the beginning of the tape, a method according to
Das in diesem Zusammenhang zu lösende technische Problem besteht in der Ausgestaltung der Bandführungskanäle, die zwangsläufig auf einer dem Verschlusskopf gegenüberliegenden Seite einen Kreuzungspunkt haben müssen. Bei dem Verfahren gemäß Patentanspruch 7 ist ein erster Bandführungskanal vorgesehen, der das Packstück umgibt sowie ein zweiter Bandführungskanal, der an den ersten Kanal anschließt und ebenfalls das Packstück umgibt. Theoretisch können auch weitere Bandführungskanäle vorgesehen sein, um nicht nur Doppel-, sondern Dreifach- oder Vierfachumreifungen vorzunehmen. Der technische Aufwand bei Dreifach- oder Vierfachumreifungen wird aber sehr hoch, da sich im Kreuzungspunkt der jeweiligen Bandführungskanäle Möglichkeiten ergeben müssen, um die jeweils innenliegenden Bandführungskanäle zu öffnen, wenn der Verschlusskopf das Umreifungsband spannt.The technical problem to be solved in this context is the design of the tape guide channels, which inevitably have to have a crossing point on a side opposite the closure head side. In the method according to
Kern des Verfahrens gemäß Patentanspruch 7 ist daher, dass ein dem Verschlusskopf gegenüberliegender Kreuzungsbereich der Bandführungskanäle freigegeben wird. In einer ersten Ausführungsform ist der innenliegende, dem Packstück nähere Bandführungskanal geteilt ausgeführt, wobei wenigstens einer seiner Teilabschnitte aus dem Kreuzungspunkt herausbewegt wird. Wenn der Kreuzungspunkt freigegeben ist, kann das Umreifungsband in den Verschlusskopf gezogen und somit gespannt werden.The core of the method according to
An den Bandführungskanälen sind federbelastete Haltemittel für das Umreifungsband vorgesehen, die sich unter Überwindung der Federkraft selbsttätig öffnen und das Umreifungsband freigeben, damit es an dem Packstück zur Anlage gelangen kann.At the tape guide channels spring-loaded holding means are provided for the strapping, which open automatically overcoming the spring force and release the strapping, so that it can get to the package to the plant.
Theoretisch ist es möglich, beide Bandführungskanäle so zu gestalten, dass sie im Kreuzungspunkt geöffnet werden, beispielsweise wenn stangenförmige Packstücke gewissermaßen nicht in Axialrichtung der von den Bandführungskanälen gebildeten Öffnungen, sondern in Radialrichtung, also gewissermaßen quer zu den Bandführungskanälen in die Umreifungsvorrichtung eingebracht werden sollen. Für die Funktion der Doppelumreifung ist es allerdings lediglich erforderlich nur den innenliegenden Bandführungskanal so auszubilden, dass der Kreuzungspunkt freigebbar ist.Theoretically, it is possible to make both tape guide channels so that they are opened at the intersection, for example, if rod-shaped packages are to be introduced in a sense not in the axial direction of the openings formed by the tape guide channels, but in the radial direction, so to speak, transversely to the tape guide channels in the strapping. For the function of Doppelumreifung, however, it is only necessary to form only the inner band guide channel so that the intersection point is releasable.
Während bei der vorgehend beschriebenen Ausführungsform davon ausgegangen wird, dass ein innen liegender und wenigstens ein weiterer, außen liegender Bandführungskanal vorgesehen ist, besteht die Alternative gemäß Patentanspruch 9 darin, die Bandführungskanäle starr auszubilden und im Kreuzungspunkt miteinander zu verbinden. Hierzu ist ein Kreuzungsteil vorgesehen. In dem Kreuzungsteil gibt es ebenfalls einen innen liegenden und einen außen liegenden Bandkanal, der jeweils mit dem ersten und zweiten Bandführungskanal verbunden ist. Das Wesentliche ist jedoch, dass nicht der ganze Bandkanal aus dem Kreuzungspunkt herausbewegt werden muss, sondern, dass nur ein den inneren Bandkanal von dem äußeren Bandkanal trennender Schieber geöffnet werden muss, um sowohl das innenliegende Umreifungsband als auch das außen liegende Umreifungsband aus den jeweiligen Bandkanälen und den Bandführungskanälen herauszuziehen. Ein solcher Schieber hat den Vorteil, dass es sich um ein wesentlich kleineres bewegliches Bauteil handelt, als bei einem ganzen Bandführungskanal. Daher sind auch nur kleinere Antriebseinheiten erforderlich. Die Bauweise ist kompakter. Das liegt auch daran, dass der Schieber während des Einlaufens des Bandes zwei Funktionen hat: Er ist einerseits Wandung des äußeren Bandkanals aber gleichzeitig auch Begrenzung des inneren Bandkanals. Vorzugsweise ist der Schieber sogar U-förmig konfiguriert, so dass er wie eine Gabel drei Wände des inneren Bandkanals innerhalb des Kreuzungsbereichs bildet. Durch zurückziehen des Schiebers wird dann gleichzeitig sowohl der innere als auch der äußere Bandkanal freigegeben.While in the embodiment described above, it is assumed that an inner and at least one further, outer band guide channel is provided, the alternative according to
Ein weiteres wesentliches Element bei dieser Art der Bandführung ist, dass das Umreifungsband nach Verlassen des ersten Bandführungskanals in den zweiten Bandführungskanal eintritt, und zwar über einen Bypasskanal, der entlang des Verschlusskopfes verläuft. Der Bypasskanal ist mit dem Ende des ersten Bandführungskanals und dem Anfang des zweiten Bandführungskanals verbunden. Dieser Bypasskanal wird vorzugsweise so nahe wie möglich an dem Bandein- und Auslaufkanal des Verschlusskopfes positioniert, damit der Abstand der Bandschlaufen möglichst gering ist. Auf diese Weise wird sichergestellt, dass sich die Umreifung nicht durch seitliche Verlagerung einer oder beider der Bandschlaufen lockert, mit der Folge, dass die Vorspannung der Umreifung nachlässt.Another essential element in this type of tape guide is that the strapping enters after entering the first band guide channel in the second band guide channel, via a bypass channel which extends along the closure head. The bypass channel is connected to the end of the first tape guide channel and the beginning of the second tape guide channel. This bypass channel is preferably positioned as close as possible to the tape inlet and outlet channel of the closure head, so that the distance of the belt loops is minimized. In this way it is ensured that the strapping does not loosen by lateral displacement of one or both of the strap loops, with the result that the bias of the strapping decreases.
Es wird in diesem Zusammenhang als besonders vorteilhaft angesehen, wenn der Bypasskanal nach dem Anlegen der Bandschlaufen geöffnet wird und die Bandschlaufe aus dem Bypasskanal in Richtung des Bandein- und Auslaufkanals des Verschlusskopfes verlagert wird. Diese Maßnahme kann bei verkleinerter Bandschlaufe vor dem Spannen des Umreifungsbandes erfolgen. Unabhängig davon wird es als zweckmäßig angesehen, wenn die verschobene Bandschlaufe nach dem Verlagern in den Bereich des Bandein- und Auslaufkanals von wenigstens einem Sperrelement daran gehindert wird, aus dieser Lage wieder in den Bypasskanal zu gelangen. Das Sperrelement ist vorzugsweise eine Sperrklinke, die mechanisch mit einem Schubelement gekoppelt ist, welches zur Verlagerung der zweiten Bandschlaufe in den Bandein- und Auslaufkanal eingesetzt wird.It is considered in this context to be particularly advantageous if the bypass channel is opened after the application of the belt loops and the belt loop is displaced from the bypass channel in the direction of the tape inlet and outlet channel of the closure head. This measure can be done with a reduced band loop before tightening the strapping. Regardless of this, it is considered expedient if the displaced belt loop is prevented from displacing out of this position into the bypass channel after being displaced into the region of the belt inlet and outlet channel by at least one blocking element. The blocking element is preferably a pawl which is mechanically coupled to a pusher element which is used to displace the second band loop into the band inlet and outlet channel.
Nachdem beide Bandschlaufen des vorgespannten Umreifungsbands sicher positioniert sind, erfolgt nach dem Spannen des Umreifungsbands in bekannter Weise das Verbinden der Bandenden, innerhalb des Verschlusskopfes. Dies kann stoffschlüssig, formschlüssig durch unmittelbares Verpressen oder unter Verwendung von Verschlusshülsen erfolgen.After both strap loops of the pre-strapped strap are securely positioned, after tightening the strapping band in a known manner, the joining of the strap ends, within the closure head. This can take place cohesively, positively by direct compression or by using closure sleeves.
Die Umreifungsvorrichtung gemäß Patentanspruch 14 ist dafür vorgesehen, das Verfahren gemäß Patentanspruch 1 durchzuführen. Es handelt sich um eine automatisierte Vorrichtung, bei welcher der komplette Umreifungsvorgang von einer Steuereinheit gesteuert wird. Die Umreifungsvorrichtung ist hierzu mit entsprechenden Aktoren und Sensoren versehen, die mit der Steuereinheit verbunden sind.The strapping device according to
Die erfindungsgemäße Umreifungsvorrichtung umfasst in dieser Ausführungsform eine Greifeinheit, welche Mittel aufweist, einen aus dem Verschlusskopf herausgeschobenen Bandanfang zu greifen und mehrfach um das Packstück herumzuführen und den Bandanfang schließlich wieder dem Verschlusskopf zuzuführen. Die Greifeinheit ist an einem in einer Drehbewegung um das Packstück versetzbaren Führungsring angeordnet. Der Verschlusskopf ist aus der Bewegungsbahn der Greifeinheit verlagerbar, um nach dem Anlegen der ersten Bandschlaufe nicht mit der Greifeinheit in Kontakt zu gelangen. Eine Verlagerung der Greifeinheit ist ebenfalls möglich. Nach dem Anlegen einer zweiten oder weiteren Bandschlaufe befindet sich die Greifeinheit vor der Bandeinlaufseite des Verschlusskopfes. Eine Transportvorrichtung ist zwischen dem Verschlusskopf und die Greifeinheit einbringbar um den Bandanfang in die Bandeinlaufseite des Verschlusskopfes zu transportieren.The strapping device according to the invention comprises in this embodiment, a gripping unit, which has means to grab a pushed out of the closure head strip beginning and perform several times around the package and finally feed the tape back to the closure head. The gripping unit is arranged on a displaceable in a rotational movement about the package guide ring. The closure head can be displaced out of the movement path of the gripping unit in order not to come into contact with the gripping unit after the application of the first belt loop. A displacement of the gripping unit is also possible. After the application of a second or further band loop, the gripping unit is located in front of the band inlet side of the closure head. A transport device can be introduced between the closure head and the gripping unit in order to transport the beginning of the strip into the band inlet side of the closure head.
In der alternativen Ausführungsform gemäß Patentanspruch 20 wird das Bandende nicht durch eine Greifeinheit geführt, sondern durch Bandführungskanäle, welche das zu umreifende Packstück zweifach umgeben. Die Anordnung und Funktionsweise der Umreifungsband führenden Kanäle wurde vorstehend erläutert.In the alternative embodiment according to
Der dem Packstück benachbarte innere Bandführungskanal ist in einer ersten Ausführungsform geteilt, so dass wenigstens einer seiner Teilabschnitte aus dem Kreuzungsbereich heraus bewegbar, insbesondere herausschwenkbar ist. Beim Herausbewegen bzw. Herausschwenken der Teilabschnitte wird das Verpackungsband von umgebenden Teilen befreit und kann bis zur Anlage am Packstück aus dem Bandführungskanal heraus gezogen werden.The inner band guide channel adjacent to the package is divided in a first embodiment so that at least one of its sections can be moved out of the crossing region, in particular swung out. When moving out or swinging out of the sections of the packaging tape is freed from surrounding parts and can be pulled out of the band guide channel until it rests on the package.
In der alternativen Ausgestaltung gemäß Patentanspruch 20 kommt in einem Kreuzungsteil ein den äußeren vom inneren Bandkanal trennender Schieber zum Einsatz, welcher vorzugsweise U-förmig konfiguriert ist und einen Teilabschnitt des inneren Bandkanals bildet. Der Schieber deckt dabei durch die U-förmige Geometrie den oberen Bandkanal nach oben ab.In the alternative embodiment according to
Während dieser Schieber lediglich dafür vorgesehen ist, das Umreifungsband im Kreuzungspunkt freizugeben, damit es beim Spannen am Packstück zur Anlage gelangen kann, soll das Schubelement gemäß Patentanspruch 27 das Umreifungsband aus dem Bypasskanal in den Bandein- und Auslaufkanal verlagern. Ein Zurückgleiten der verlagerten Bandschlaufe wird durch ein Sperrelement verhindert, welcher das Umreifungsband auch dann in dem Bandein- und Auslaufkanal hält, wenn das Schubelement zurückgezogen wird.While this slide is only intended to release the strapping at the intersection so that it can come to rest during clamping on the package, the thrust element according to

Die Umreifungsvorrichtung 1 umfasst ferner einen Führungsring 6 der das Packstück 5 umgibt und um seine Längsachse L drehbar gelagert ist. Mit dem Führungsring 6 ist eine Greifeinheit 7 ortsfest verbunden. Wenn der Führungsring 6 in eine Drehbewegung versetzt wird, rotiert auch die Greifeinheit 7 um die Längsachse L und damit um das Packstück 5.The strapping
Die Greifeinheit 7 ist dafür vorgesehen, ein von dem Verschlusskopf 4 ausgegebenes Umreifungsband 17 an seinem Bandanfang 31 zu greifen und klemmend zu fixieren. Zu diesem Zweck ist die Greifeinheit 7 mit einer Klemmbacke 8 versehen. In diesem Ausführungsbeispiel würde die Klemmbacke 8 auf die breiteren Flachseiten des Umreifungsbands 17 wirken. Alternativ kann die Klemmbacke 8 auch auf eine Schmalseite des Bandanfangs 31 wirken.The
Nachdem der Bandanfang 31 in der Greifeinheit 7 festgeklemmt worden ist, wird über den Verschlusskopf 4 Umreifungsband 17 ausgegeben und der Führungsring 6 angetrieben, so dass sich die Greifeinheit 7 mit dem nicht näher dargestellten Bandanfang in Richtung des Pfeils P bewegt. Da die Greifeinheit 7 zur Aufnahme des Bandanfangs an einer gegenüber dem Verschlusskopf 4 angeordnet sein muss, ist es erforderlich den Verschlusskopf 4 noch vor der ersten vollständigen Umrundung der Greifeinheit 7 aus der mit unterbrochener Linie eingezeichneten Bewegungsbahn B herauszubewegen, damit die Greifeinheit 7 nicht mit dem Verschlusskopf 4 kollidiert. Zu diesem Zweck wird bei dieser Ausführungsform das Gestell 2 mit dem Ausleger 3 und dem Verschlusskopf 4 um eine Horizontalachse in Richtung des Pfeils P1 verschwenkt (

In nicht näher dargestellter Weise wird die Klemmbacke 43 unter dem Einfluss einer Federkraft in Richtung auf die Stützbacke 42 gedrückt.In a manner not shown, the clamping
Nachdem die Greifeinheit 7 eine zweite oder auch dritte oder vierte Umrundung des Packstücks nahezu vollständig vollzogen hat, wird der Verschlusskopf 4 zurückgeschwenkt und die Greifeinheit 7 in der in

Dadurch ergibt sich die in
Um den Abstand A zwischen den oberen beiden Bereichen der beiden Bandschlaufen 15, 16 zu verringern ist es vorgesehen, den in einem Bypasskanal 28 parallel zum Verschlusskopf 4 verlaufenden Bereich der Bandschlaufen 15, 16 in Richtung der Bandschlaufe im Bandein- und Auslaufkanal 29 des Verschlusskopfes 4 zu verlagern.In order to reduce the distance A between the upper two regions of the two
