A device for shrinking a heat-shrink film placed around a palletized stack of goods includes a shrinking frame movable on a rack in vertical direction and forming an opening for the stack of goods. A shrinking device for shrinking the heat-shrink film includes a surrounding side wall, forming a shrinking space, comprising a shrink hood open downward and a cover. The shrink hood is movable in the vertical direction, and includes a blower that generates an air flow in the interior of the shrink hood. The blower includes an impeller driven by a drive. At least one air-guide section includes a nozzle on its end opposite the impeller, so that the air suctioned by the impeller from the shrinking space surrounded by the shrink hood can be reintroduce in a directed manner via the nozzle into the shrinking space surrounded by the shrink hood.
A device (1) for the shrinking of a heat-shrink film (3) placed around a stack of goods (2), with a shrinking frame (5), movable on a rack (4) in vertical direction between an upper position and a lower position, forming an opening (19) for the stack of goods (2), on which at least one shrinking device for the shrinking of the heat-shrink film (3) is provided, wherein the device (1) includes a surrounding side wall (7), forming a shrinking space, comprising a shrink hood (6) open downward, as well as a cover (8), wherein the shrink hood (6) is movable in the vertical direction, and wherein the device (1) furthermore includes at least one blower (9) that generates an air flow in the interior of the shrink hood (6), wherein the at least one blower (9) includes an impeller (20) driven by a drive (10), wherein the impeller (20) of at least one blower (9) is connected to at least one air-guide section (11), wherein the at least one air-guide section (11) is respectfully connected to at least one nozzle (12) on an end thereof opposite the impeller (20) so that the air suctioned by the impeller (20) from the shrinking space surrounded by the shrink hood (6) can be reintroduce in a directed manner via the at least one nozzle (12) into the shrinking space surrounded by the shrink hood (6).
A method for shrinking a heat-shrink film (3) placed around a stack of goods (2), using a device (1), with a shrinking frame (5), movable in vertical direction between an upper position and a lower position, forming an opening (19) for the stack of goods (2), on which at least one shrinking device is provided for shrinking the heat-shrink film (3) by heating, wherein the device (1) includes a surrounding side wall (7), forming a shrinking space, comprising a shrink hood (6) open downward, as well as a cover (8), wherein the shrink hood (6) is movable in vertical direction, and wherein the device (1) furthermore includes at least one blower (9) generating an air flow in the interior of the shrink hood (6), wherein the at least one blower (9) includes an impeller (20) driven by a drive (10), using the device (1), wherein on the impeller (20) of the at least one blower (9) is connected to at least one air-guide section (11), which is respectfully connected to at least one nozzle (12) on an end opposite the impeller (20) so that the air in the shrinking space enclosed by the shrink hood (6) that is suctioned out by the impeller (20) is reintroduced in a targeted via the at least one nozzle (12) into the shrinking space surrounded by the shrink hood (6).
