Embodiment Construction

[0051] The same reference numerals are used for the same or the same elements of the present invention. In addition, for the sake of clarity, only the reference numerals necessary for describing each drawing are shown in each drawing. The illustrated 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 it is not a closed limitation.

[0052] figure 2 In the schematic diagram, a contraction device 1* with energy management according to the invention is shown. The shrinking device 1* is mostly the same as the shrinking device 1 known from the prior art (refer to figure 1 ) Is similar, so you can refer to its description. The throttle valves 22a and 22b are respectively equipped with adjusting drivers 40a and 40b, and the throttle valves 22a and 22b can be opened or closed by means of the adjusting drivers. The adjusting drives 40a, 40b are connected to the control unit 50, so that th...

Abstract

The invention relates to a shrinking device (1*) provided with a conveying device (10) for an item or an item set and provided with at least one device (18) used for producing shrinking medium. The shrinking medium is divided into two shrinking medium sub stream through at least one dividing device. The first sub stream can be conveyed into the at least one first heating device (15). The item or the item set (5) is loaded by the aid of the shrinking medium from side faces or from the above through the heating device. The second shrinking medium sub stream can be conveyed to the at least one second heating device (16). The conveying device (10) is heated by the aid of the second heating device (16) and / or the item or the item set is loaded from the lower side or from the below through the conveying device (10). According to the invention, the dividing device is at least one and is used for controlling the shrinking medium stream to be divided into at least two shrinking medium sub streams automatically. The invention also relates to a method used for adjusting operation statuses of the shrinking device (1*) provided with the conveying device (10).

Description

Technical field [0001] The present invention relates to a shrinking device and method according to the features of the preambles of claims 1 and 8, which is used for heat shrinking a film around an article or a collection of articles. Background technique [0002] When packaging items, especially beverage containers, bottles, etc., into a bundle, these items are put together in a desired manner and wrapped with shrink film. By inputting a shrinking medium, such as hot air, the shrink film is heat-shrinked around the article in the shrinking channel. [0003] figure 1 In the schematic view, a shrinking device 1 known from the prior art is shown. Items, especially beverage containers, bottles 6, cans, etc., are put together in groups and wrapped with shrink film 7. The set of wrapped items is also called strapping 5. The tying 5 is conveyed in the conveying direction TR via the input area 3 into the shrinking channel 2 on a conveyance, in particular a conveyor belt 10 or the like....
