Definitions

  • the invention relates to a packaging machine and a method for its control.
  • the packaged goods can be, for example, containers with a plurality of regularly arranged beverage containers, which are wrapped with a disposable film packaging, with which they are stacked on pallets in order to be better handled during storage and transport.
  • the packaging film is applied by means of suitable packaging machines, with the aid of which the packaging to be wrapped in each case with a film section previously separated by a continuous web is taken. This impact is normally continuous, i. during ongoing transport of the container, wherein the cut to length film sections are usually supplied from an area below the transport level of the container, so that the container is pushed onto a portion of the film section, which later forms the bottom portion.
  • the film sections are conveyed by means of a plurality of guiding and / or deflecting elements on the conveyor belt and to a wrapping element, which is movably above the container and during their transport strikes the foil sections around the container, so that they are largely completely enveloped.
  • Such a continuous device for packaging items at risk of tilting by means of a film wrapping is, for example, from the DE 42 07 725 C2 out.
  • the containers are transported in multiple lanes through the packaging machine.
  • at least two containers are simultaneously at least partially wrapped by the packaging film at the same time in a wrapping process.
  • the outgoing wide film web is thus separated into at least two halves and these halves are brought to a sufficient distance to parallel to each other without mutual interference to haul transported packages.
  • Folienspreizens is usually realized in that a divided into two sheets of film is pulled over angularly employed rigid spreader rollers. In order to minimize the friction of the film to the rigid rollers, they are provided in a portion of its circumference with holes from which air flows. This subregion corresponds at least to the wrap angle of the film. As a result, the pressurized air roller forms an air bearing for the film web.
  • Alternative variants may provide for dispensing with the airbed and merely guiding and pulling the film over a curved shaft.
  • this variant has the disadvantage that the film charges statically and the spread can assume only a small Sp Dahl hindered light, so that a film spacing of typically only about 30 mm can be realized.
  • Devices for separating material webs into two partial webs using a film spreader with rollers for film guidance are, for example, from DE 37 33 129 A1 , from the DE 42 41 354 C1 as well as from the DE 101 05 486 A1 known.
  • a device and a method for longitudinal cutting of strip material into thin strips go, for example. From DE 695 16 233 T2 out. Here, the strip material is held and guided by means of compressed air-supplied air bearings.
  • the film cut to a defined length is transported on a so-called vacuum belt in the direction of the film wrapping station. Due to the predetermined mechanism of two separate bands on the transport path from the film separation station to the vacuum belt and the conveyor belt and the film wrapping the film must be transported or pushed over an area in which no support of the film can be guaranteed. In order to bridge this area and to ensure that the film or the film beginning does not buckle due to gravity and thus causes a production disturbance, the film is stabilized with the aid of two blowpipes and transported by means of an air duct formed by the blowpipes in the desired position and orientation.
  • the systems described have the disadvantage that a compressed air system must be available.
  • the compressed air stabilization requires and conveying the film sections a relatively high compressed air consumption, so that a relatively high energy input for the production of compressed air is required.
  • a primary object of the invention is to provide an easily manageable and reliably functioning guide option for tape and film material, which is operable with a reduced energy input compared to a compressed air-supplied air bearing.
  • At least one of a plurality of guide elements for the packaging and / or film webs used as packaging is designed as an ultrasound bearing unit.
  • the present invention is thus based essentially on the use of ultrasonic air bearings as guiding, deflecting and / or bearing elements for the packaging webs to be conveyed, in particular for film sections.
  • the air is compressed between the medium to be transported and the oscillator, thus achieving a certain load capacity. This load capacity is sufficient in practice to guide the very light packaging or film webs at a sufficient distance from the bearing or guide elements.
  • the present invention thus relates essentially to the guide, deflection and bearing elements for the packaging webs used. However, it relates in the same way to a machine for packaging goods and / or packaging units with a sheet-like packaging web such as a disposable film o. The like.
  • This machine comprises a feed unit for the packaging webs and a wrapping unit for at least partially wrapping the goods or packaging units the packaging web.
  • the packaging webs are guided over planar, web-like and / or roller-like guide elements and / or carried on these at least in sections.
  • the invention is characterized in that at least one of the guide elements is formed as an ultrasonic storage unit.
  • the at least one ultrasound bearing unit may be formed by a deflecting element arranged substantially transversely to a conveying direction of the packaging web.
  • a deflecting element is comparable to a deflection roller used in conventional machines, which may optionally have a compressed air supply to improve the film guide.
  • the machine according to the invention is on the Compressed air supply omitted because the ultrasonic bearing unit ensures the necessary distance of the guide element to the packaging web and thus for the desired reduction of the frictional resistances.
  • the deflecting element can form a largely non-contact, line-like deflection and / or guidance for the packaging web.
  • two or more deflecting elements arranged at an angle to one another can form a spreader unit for the spaced guidance of two or more packaging webs previously conveyed in parallel and / or as a single packaging web.
  • the ultrasonic bearing units are also suitable for forming at least one surface with a planar guide for the packaging web or the film web.
  • the at least one ultrasound bearing unit is preferably formed by an ultrasonic air bearing, the activation of which triggers a compression of the air between the packaging web and the surface of the ultrasound bearing unit.
  • the vibrator, vibrator and vibration isolation system is available and can be dimensioned and configured as needed.
  • the execution of the vibrator or the oscillating body is to be executed user-specific, for example. As a cylindrical roller or as a flat plate.
  • the invention describes the use of the system in a packaging machine for handling the packaging films or webs in the functional areas of spreading the film and transporting the film.
  • packaging films or other suitable packaging webs for example of paper or of a suitable composite material, which are suitable for the purpose of wrapping and packaging of packaging goods such as e.g. Containers with beverage containers are suitable. If a conventional packaging film is used as the packaging material, it is normally shrunk around the packaging material after the packaged product has been impacted by the action of heat.
  • the present invention also relates to a method for packaging goods and / or packaging units with a sheetlike packaging web such as a disposable film or the like, in which the Packaging webs of a wrapping unit for at least partially wrapping the goods or packaging units are supplied to the packaging web.
  • the packaging webs are guided over planar, web-like and / or roller-like guide elements and / or carried on these at least in sections.
  • These guide elements are formed as ultrasonic bearing units in the form of ultrasonic air bearings whose activation triggers a compression of the air between the packaging web and the surface of the ultrasonic bearing unit.
  • the invention is based on the use of ultrasonic air bearings in packaging machines or in methods for packaging packaging goods.
  • a high-frequency oscillating component the air is compressed between the medium to be transported and the oscillator, thus achieving a desired load-bearing capacity.
  • the air-assisted, angularly adjustable and fixed Spreizumlenkungen be replaced by an ultrasonic air bearing generating system.
  • the highly compressed "air film” causes the film is pulled almost without contact on the spreader and is spread by their angular position.
  • the blowpipes which generate an "air duct", replaced by a planar vibration system, which in turn allows by an "air film” a non-contact transporting the film.
  • the main advantage of the system is the massive reduction of energy consumption, as compressed air as a supporting medium can be dispensed with.
  • the system is much more energy efficient than the previously known systems.
  • FIG. 1 shows the essential functional elements of a per se known packaging machine 10, which comprises a guide system 12 for supplying cut and / or longitudinally in two or more parallel and spaced guided divided film webs 14 to 16 containers.
  • the containers 16 are conveyed on a horizontally arranged conveyor belt 18 to the packaging station 20, where they are wrapped and enveloped by means of a Einschlag Anlagen 22 with appropriately cut film webs 14, if necessary, then subjected to a shrinkage process (not shown) by means of heat.
  • the film webs 14 are deducted in the embodiment shown before cutting in appropriately cut sections of a film drum 24, so that over a longer period of continuous feeding can be guaranteed. Before the film drum 24 is completely unrolled, another film drum 26 can be activated.
  • FIG. 2 shows in detail the film deflection of the section II of the packaging machine 10 from Fig. 1 ,
  • the film web 14 is deflected several times by means of inventive ultrasonic air bearing 28 and can be brought by introducing a suitable central incision by means of two juxtaposed and employed at a shallow angle x ultrasonic air bearing 28 at a desired distance from each other.
  • the schematic representation of Fig. 3 illustrates this so-called film spreading.
  • FIG. 4 shows a flat film guide of the section IV of the packaging machine 10 Fig. 1 .
  • the web 14 to be conveyed to the wrapping device 22 of the packaging station 20 is conveyed by means of a conveyor belt 30 of the separating station in an oblique direction up to the level of the front conveyor belt 32 for the container 16. Since the conveyor belt 30 of the separation station in front of the chain 34 of the Einschlag Anlagen 22 must end and is deflected downward, remains between the front conveyor belt 32 and the lower conveyor belt 30 of the separation station a gap within which the film web 14 should be performed to a folding or to reliably prevent any other malfunction.
  • Fig. 1 shows a flat film guide of the section IV of the packaging machine 10 Fig. 1 .
