Definitions

the invention relates to a method for helically wrapping packages or containers in a shrink-wrapping film, in which the film is pulled from at least one supply roll under tension and is guided by means of one (or more) supply roll guide device (s) around a winding cross-section which is larger than the axial package projection, and in which the packages or packages are guided through the web of the supply roll guide device (s) during the wrapping through the winding cross section.
Pre-stretched, shrink-wrapping films have found extensive use in packaging technology in recent years. Such films, for example under the trade name PRESTO-STRETCH-GARD, PRESTO-BUNDLE-GARD and PRESTO-STRETCH-GARD IV, have the property that an object covered by them is compressed due to the remaining film tension without the film tearing. This means that the packaging technology with such pre-stretchable, shrink-wrapping films differs considerably from that with heat-shrinking films, which are also used in packaging technology.
a method and a device are known (Overwrap-Equipment Co., Fairfield, NJ, USA), in which relatively long packages or containers are sent through a winding station and are encircled by a rotating film supply roll as the process proceeds from which the film is unwound.
bridging conveyor belts in the area of winding stations (cf. DE-OS 31 19 657), so that even shorter objects are transported, the bridging conveyor belt and the package / container being wrapped as the process progresses.
package is understood to mean a more or less closed, possibly bulky, but not falling apart structure, for example a carpet roll, while under a “bundle” is to be understood to mean a structure which is stacked out of cardboard boxes, objects and the like, which can be pushed down from its base when a slight force is exerted, for example by the wrapping film itself, or move without a base, so that the "bundle” so that it no longer has the original shape to be encased.
wrapping containers of the type identified above with the known methods and devices is particularly difficult since, for example, stacked, light cardboard packaging filled with plastic objects tend to wrap with a pre-tensioned stretch film from the container to be pushed out or moved.
This object is achieved according to the invention in a method for the spiral-like wrapping of packages or containers in a shrinking film, in which the wrapping is carried out simultaneously by two counter-rotating supply rolls which are arranged one behind the other in the conveying direction of the packages or containers by at least one film width .
the tension and the circulation speed of the supply rolls can be varied; however, the method is preferably used in such a way that the two supply rolls run synchronously.
the foils lay down wrinkle-free during the transport of the package / container, with a uniform distribution of force on the package / container also being achieved.
the two rolls are equipped with films of different widths and / or that the film tension of the two supply rolls is kept at different values.
the front roller in the conveying direction can be held under a slight tension, while an increased tension is applied to the subsequent supply roller.
the device for performing the method i. H.
a roller guide device with two supply rolls which rotate in opposite directions and are offset in the conveying direction by at least one film width.
the counter-rotating supply rolls are therefore preferably rotatably attached to the front and back of the rotating frame of a supply roll guide device.
a device for wrapping packages 1 is shown in perspective.
the device has a wrapping film guide device 2, with which a strip of a wrapping film 3, 3 'can be drawn off from each of two supply rolls 4, 4'.
the supply rolls 4, 4 ' are each mounted on a ring 5, 5' with a flying axis.
Each of the two rings 5, 5 ' is provided on its outside with a ring gear, with two driving pinions 6, 6' rotating in opposite directions, but driven by the same motor, rotating the two rings 5, 5 'in opposite directions. Viewed in the direction of conveyance, the ring 5 rotates clockwise and the ring 5 'rotates counterclockwise.
Two conveyor belts 7 and 8 are arranged in front of and behind the winding station equipped with the two rings 5, 5 '.
a bridging conveyor (not shown here) can convey the package or a container through the rings 5, 5 '.
the actual winding station is surrounded by a holding frame 10.
the guide devices in particular the rings 5, 5 'with the associated drive devices, are held by a supporting wall 11 which extends between the periphery of the rings and which has (not shown) support devices for the rings.
the means of rotating the wreaths and transporting the packages or containers are known per se.
the film is a so-called stretch film, that is to say a shrinking film, which is pulled off under tension from one of the supply rolls 4, 4 ', the supply rolls rotating in opposite directions during wrapping on a fixed path. Distance from package 1 is kept. The package is transported during the wrapping, so that when wrapping, two wrapping foil layers lying one on top of the other with opposite slopes result.
roller guide device here consisting of the two rings 5, 5 ', is equipped with two supply rollers which rotate in opposite directions and synchronously and are offset by at least one film width in the conveying direction.
winding axes of the supply rolls are inclined to the axis of rotation of the frame 5 or 5 'by an angle between 2 - 20 o from the parallel orientation, specifically for the roll 4 away from the package and at Roll 4 'to the package.
This inclination of the rollers causes the film to lay against the package practically without creases and without the need for additional guide and guide rollers, so that a film tube is formed particularly smoothly.
the film pre-tension which depends on the circumstances and the composition of the film material, to be different in the two films, for example the first winding roll 4 'with a slightly lower winding tension and the subsequent roll 4 with a somewhat higher winding tension to wrap.
different film widths for example initially narrow (roll 4 '), then wide (Roll 4) can be provided.
