- the object of the invention is to provide a method by means of which the aforementioned disadvantages can be avoided and which ensures adequate climate protection by improved welding of the cover sheet film and the supernatant of the heat shrink film jacket.
- the normally rapidly rising upward hot gases are guided by the combined heat deflection and pressing over the surface of the stack to the center, so that already upon shrinkage of the sides of the stack during the upward movement of the shrinking device, a preheating of the cover sheet in the Top and a preheating of the supernatant of the heat shrink film jacket takes place. At the same time the supernatant is turned inwards.
- the still not completely cooled superimposed layers of heat shrink film jacket and cover sheet film are connected by pressing together by the combined heat deflection and pressing.
- the pressure exerted during pressing together can be varied. As a result, a particularly good welding of the superposed layers and thus a very good climate protection is achieved.
- the cover sheet is at least so large that after folding the supernatant a circumferential contact between the flattened supernatant of the heat shrink film jacket and the cover sheet is guaranteed.
- the cover sheet is greater than the stack, so that the cover sheet is folded down on all sides down.
- the heat shrink film coat can also project beyond the lower edge of the stack for carrying out a lower shrinkage. If a bottom-side sealing of the stack of goods is desired, it is also possible to provide a bottom film that preferably protrudes over the edge between the pallet and the stack of goods is welded to the heat shrink film jacket when performing the Unterschrumpfes.
- the shrinking device can initially be moved upwards for carrying out the upper shrinkage and subsequently for carrying out the lower shrinkage.
- shrinkage begins at about half the height of the stack.
- the shrinking device is first moved to half the height of the stack. Then, the shrinking device is started and initially moved vertically upwards to perform the upper shrinkage and then down to carry out the undershrink.
- the supernatant of the heat-shrinkable film jacket projecting over the top edge of the product stack in particular by means of a direct or indirect outward-pointing airflow generated by the combined heat-deflecting and pressing device, to be raised.
- a fan may be provided, which is switched to raise the supernatant to bubbles.
- the airflow impinging on the upper side is deflected outwards and thus ensures an uprighting.
- the fan can be put on suction.
- the hot gases rising along the sides of the stack and diverted in a direction parallel to the top of the stack can be sucked off, in particular by means of the combined heat deflection and pressing device.
- other embodiments are conceivable.
- the superimposed layers of heat shrink film and cover sheet can be connected at least in the top of the stack by pressing the not completely cooled superimposed layers of heat shrink film and cover sheet.
- the superimposed layers of heat-shrinkable film jacket and cover sheet film can be connected, at least in the area of the upper side of the product stack, by pressing on the layers of heat-shrinkable film jacket and cover sheet film which have not yet completely cooled.
- the invention also relates to a device for shrinking a heat-shrinkable film jacket placed around a, in particular palletized, stacked stack, with at least one shrinking device which can be moved vertically on a frame, in particular as shrink frame, for shrinking the heat shrinkable film jacket by heating, the heat shrinkable film jacket at least over the top edge protruding from the top of the stack for supersaturation shrinkage and on the top of the stack of goods, a preferably over the edge of the stack of goods Hende, cover sheet is arranged, which is welded to the heat shrink film jacket.
- Such devices are used for example in the paper industry.
- pallets with substandard format dimensions are used, which have to be packaged on a shrink packaging line.
- the shrinkage takes place after placing the cover sheet on the top of the stack and the subsequent provision of the heat shrink film jacket.
- the overhanging ends or edges of the cover sheet film and a possibly additionally provided between the pallet and stack of goods bottom sheet are thereby trapped between the heat shrink film jacket and the stack or the pallet.
- adequate climate protection must be ensured. This is only the case if sufficient welding is ensured between the cover sheet film placed on the stack and the heat-shrinkable film jacket designed as a band.
- the object of the invention is to provide a device by means of which the aforementioned disadvantages can be avoided and which ensures shrinkage with adequate climate protection by improved welding of the cover sheet film and the supernatant of the heat shrink film jacket.
- the hot gases which normally rise rapidly upward are guided toward the center by the combined heat deflection and pressing device over the surface of the product stack, so that already during the shrinkage of the sides of the product stack during the upward movement of the shrinking device a preheating of the cover sheet in the Area of the top and a preheating of the supernatant of the heat shrink film jacket done. At the same time the supernatant is turned inwards.
- the still not completely cooled superimposed layers of heat shrink film jacket and cover sheet film are connected by pressing together by the combined heat deflection and pressing.
- the pressure exerted during pressing together can be varied. As a result, a particularly good welding of the superposed layers and thus a very good climate protection is achieved.
- the cover sheet is at least so great that after
- the cover sheet is larger than the stack, so that the cover sheet is folded down on all sides down.
- the heat shrink film coat can also project beyond the lower edge of the stack for carrying out a lower shrinkage. If it is also desired to seal the stack on the underside, a bottom film that preferably protrudes over the edge can also be provided between the pallet and the stack, which is welded to the heat shrink film jacket when the undershrink is carried out.
- At least the area of the combined heat deflection and pressing device that can be brought into contact with the upper side of the stack is a little smaller than the inner dimensions of the shrinkage device, so that a sufficient movability of the shrinkage device during the upper shrinkage is ensured.
- the plate may preferably have a coating, preferably a Teflon coating, on the side facing the good stack.
- the side edges of the combined istur- and pressing device can be aligned approximately with the side edges of the stack. But it is also quite conceivable that the combined heat deflection and pressing device are a little smaller than the dimensions of the stack of goods. In such a case, suitable means should be provided which allow a deflection of the hot gases.
- the combined heat deflection and pressing device preferably projects laterally over the contour of the stack of goods.
- the combined Hopkinsumlenk- and pressing device may have at least one, preferably arranged approximately in the middle of the combined heat deflection and pressing, recess for the exit of parallel to the top of the stack in the direction of the center flowing hot gases upwards. Through the recess, the transferred hot gases, which flow from the edge of the upper side in the direction of the center of the upper side, are discharged upward.
- the existing flow velocities also reinforce the folding of the supernatants and the welding of the supernatant with the cover sheet.
- two successively arranged recesses are provided.
- the position of at least one recess for changing the point at which the hot gases initially flowing parallel to the upper side of the stack of goods can be changed upwards can be changed.
- the recess is for example part of a cover plate or a sliding plate, which is movable in the horizontal direction with respect to the bathumlenk- and pressing device within a contour of an opening provided in the Wärmumlenk- and pressing.
- a conveying device for sucking off the hot gases flowing parallel to the upper side of the stack in the direction of the center of the stack can be provided via at least one recess.
- the conveyor causes a negative pressure in the region of the top of the stack and thus sucked and deflected a larger amount of hot gases in the area between the top and combined istumlenk- and pressing.
- the conveyor can also be used for blowing, which serves for the initial eventual erection of the supernatant of the heat-shrinkable film jacket.
- a throttle valve may be provided in the region of at least one recess. This is when placing the combined heat deflection and pressing device and thus when pressing the not completely cooled superimposed layers of heat shrink film jacket and cover sheet in the closed position. This prevents the cover sheet in the region of the recess from being pulled upwards by the thermals of the warm air rising from the heated cover sheet surface.
- the throttle valve also allows control of the volumetric flow during shrinkage.
- At least the area of the combined heat deflection and pressing device that can be brought into contact with the not yet completely cooled superimposed layers of heat shrink film jacket and cover sheet film can be cooled. It is conceivable, e.g. a cooling system provided in the region of the underside of the combined heat-deflection and pressing device, which is cooled with water, air or another suitable cooling medium.

- the heating strip which can be moved in relation to the remaining shrink frame may be arranged on at least one rail provided on the remaining shrink frame and a drive may be provided for a method.
- the Rail may be mounted on either the top or the bottom of the shrink frame with the heater bar secured to the rail by appropriate means. It is also conceivable that the heating bar has rollers at both ends, which travel on a rail mounted on the upper side of the shrink frame. Also, a kind of conveyor belt is conceivable, which is guided between two pulleys and to which the heating bar is attached.
- a device In order to ensure that the combined heat deflection and pressing device has an approximately horizontal orientation, in particular in the state applied to the upper side of the stack, a device can be provided which tilts the combined heat deflection and pressing device, in particular adjacent to the top of the stack Condition, prevented.
- At least one heating strip can consist of several heating segments, preferably of several separately activatable heating segments. In the case of a separate activation, the heating segments can be separately switched on or off.
- Such an embodiment lends itself to, since then the heating segments of the heating strips are deactivated, which no longer act on the area, by the movable (s) heating bar (s) and optionally by the non-movable (s) heating bar (s) or partial areas be included by this (of these).

- the distance is about 500 mm.
- the distance is reduced to about 200 mm.
- the conveyor 20 is already set to suction, so that along the sides upwardly flowing hot gases (arrows 30) are deflected in a direction parallel to the top of the stack 1 (arrow 32).
- the heat-shrinkable film jacket 2 and the cover sheet film 6 in the region of the upper side is heated sufficiently for a good upper shrinkage.
- the shrink frame 14 has reached its uppermost position.

- the shrink frame 14 and the heat deflection and pressing device 15 is again shifted to the position shown in FIG. 7 and the wrapped and shrunk stack 1 is transported away by means of the conveyor 4.
- FIGS. 9 to 14 show a further exemplary embodiment of the device according to the invention.
- the heating bar 14a oriented orthogonally to the conveying direction 35 is designed to be movable relative to the remaining shrink frame 14. This allows an adjustment of the distance between the stack 1 on the one hand and the movable heating bar 14a of the shrinking frame 14 designed as a shrinking device. Such movability is offered when goods stack 1 different dimensions, such as length, to be packed.
- FIGS. 9, 10 and 14 show a stack 1 of lesser length. Therefore, the left heating strip 14a shown in FIGS. 9 and 10 has been moved in the direction of the opposite heating strip 14a in a direction of movement 36 oriented essentially orthogonal to this side surface. In this case, the conveying direction 35 and the direction of travel 36 are the same.

- the stack 1 is placed so that the center between the recesses 17 with the center of the top of the stack 1 is aligned approximately coincident.
- the operating situation shown in FIG. 12 for a longer stack of goods 1 and in FIG. 10 for a shorter stack of goods 1 corresponds approximately to the operating situation illustrated in FIG. 2.
- a device 41 is provided. This device 41 is provided in the region of the edge of the plate 16, which projects laterally in comparison to the other edges of the plate 16 with respect to the stack 1 most.
- the device 41 is formed as a cylinder 42 which engages a connected to the plate 16 lever arm 43 and so the plate 16 is raised in the region of this edge.
- the plate does not tilt 16 but is held in an approximately horizontal orientation, so that acts on each point of the top of the stack 1 in about the same force.
- a plurality of heating strips 14a are movable, it makes sense if a device 41 is provided in the region of each edge of the plate 16, to which a movable heating strip 14a adjoins.
