Embodiment Construction

[0051] The same reference symbols are used for identical or identically acting elements of the invention. Furthermore, for the sake of clarity, only the reference numerals necessary for describing the individual figures are shown in the individual figures. The illustrated exemplary embodiment is only an example to describe how the device according to the invention or the method according to the invention can be constructed, but is not intended to be a closed limitation.

[0052] figure 2 A shrinking device 1* with energy management according to the invention is shown in the schematic diagram. This shrinking device 1* is largely identical to shrinking devices 1 known from the prior art (cf. figure 1 ) are similar, so refer to its description. The throttle valves 22a, 22b are each equipped with an adjusting drive 40a, 40b, by means of which the throttle valves 22a, 22b can be opened or closed. The adjusting drives 40 a , 40 b are connected to a control unit 50 , so that the...

Abstract

The device (1') has a conveying device (10) for an article such as beverage container, and a fan (18) for creation of contraction medium (19) such as hot air. A heating coil (20) is arranged for controlling the temperature of the contraction medium, and a division device is arranged for division of the contraction medium into two sub-streams. A set of heating units or nozzle surface (15) is arranged, where one of the heating unit is arranged for heating the conveying device. The division device comprises a control unit for automated control of division of the medium into two sub-streams. An independent claim is also included for a method for adjusting different operating modes of a contraction device.

Description

technical field [0001] The invention relates to a shrinking device and a method according to the features of the preambles of claims 1 and 8 for thermally shrinking a film around an object or a collection of objects. Background technique [0002] When packing articles, in particular beverage containers, bottles, etc. into bundles, these articles are put together in the desired manner and wrapped with shrink film. The shrink film is thermally shrunk around the object in a shrink tunnel by feeding a shrink medium, for example hot air. [0003] figure 1 A shrinking device 1 known from the prior art is shown in a schematic illustration. Articles, in particular beverage containers, bottles 6 , cans etc. are put together in groups and wrapped with shrink film 7 . A wrapped set of items is also known as a bundle5. The bundle 5 is transported on a transport means, in particular a conveyor belt 10 or the like, into the shrinking tunnel 2 along the transport direction TR via the i...
