The present invention relates to a kind of compressive shrinkage machines for the film shrink by surrounding article or article assembly set.Compressive shrinkage machines to comprise at least one transmission section having for article or article assembly set room and at least one will be for shrinking the parts in medium transport to compressive shrinkage machines in room.Interior room comprises at least one, and preferably at least two have the first length and at least one borehole wall towards the nozzle face of room in compressive shrinkage machines each.Nozzle face comprises multiple nozzle towards article or article assembly set orientation, and it is arranged to the nozzle rows of preferred parallel.By nozzle, shrink medium streamwise and guide to interior room from the borehole wall.
According to the present invention ground, at least one nozzle face for the borehole wall is attached troops to a unit at least one movable cover fillet.Cover fillet has the second length, and it is to a great extent corresponding to the first length of the borehole wall.In the first control position, cover fillet is attached troops to a unit to a great extent in the upper seamed edge of the borehole wall.If whole side wall surface is configured to nozzle face in the corresponding borehole wall, so cover at least one at the first control position cover fillet, preferably the upper nozzle row of at least two or at least three boreholes wall or nozzle face.If only lower area in the corresponding borehole wall, the bottom 80% of such as side wall surface is configured to nozzle face, and so in the first control position, cover fillet can be arranged in above nozzle face as follows, that is, do not have nozzle rows to be covered.
At least the second control position can be pushed into by vertical motion cover fillet, before in this second control position, cover fillet is placed at least one nozzle rows and with this nozzle rows separately.Cover fillet comprises at least one following subregion, and shrinking medium cannot through in this subregion, thus the flow direction shrinking medium turns in this subregion.Especially on the height of nozzle face, do not shrink medium directly impacts on article or article assembly set, wherein, the height of nozzle face is furnished with now at least one cover fillet for contraction medium at least one subregion not transparent.Spacing between nozzle face and cover fillet is selected as follows, namely, shrink medium freely to overflow from by the nozzle rows that covers, but to bump against on cover fillet and turn to up or down thus and therefore to flow into or import in interior room in room above cover fillet and/or at least one subregion of below.Spacing between preferred nozzle face and cover fillet is 0.5 times of at least nozzle diameter.Therefore the Special Areas of article or article assembly set at least compressive shrinkage machines along transport section subregion in protected targetedly and by shrink flowing directly into of medium affect.
If shrinkable film is retracted as packaging with surrounding article assembly set in compressive shrinkage machines, so first shrinkable film is wrapped in thin-film package equipment, with surrounding this article assembly set.In side direction, so-called film eye stays open.Wrapped article assembly set is as follows along the transport section transport in compressive shrinkage machines, that is, film eye is arranged in and is parallel in the plane of the borehole wall.The axis of film eye is correspondingly arranged perpendicular to the borehole wall.Film eye is limited by upper film clothing and lower film clothing.Upper film clothing should not be pressed downwardly in compressive shrinkage machines, shrinks medium via in film eye inflow article assembly set because which hinders.Contraction medium between the article flowing into article assembly sets is necessary, to obtain best contraction result from inner heat shrink film.Be favourable as follows based on this reason, that is, be in from least one and upper film clothing the contraction MEDIA FLOW flowed out the nozzle rows of sustained height and can be covered by cover fillet, because upper film clothing can be stablized thus.
When the first embodiment, wherein whole side wall surface is configured to nozzle face, second control position corresponding to the location of cover fillet on following height, in this second control position cover fillet attach troops to a unit now in the first control position by least one nozzle rows below the nozzle rows that covers.In the second embodiment situation, wherein only the subregion of the bottom of side wall surface is configured to nozzle face, and cover fillet can such as be arranged in the second control position as follows, that is, only the nozzle rows on top is covered.According to width and the vertical location of cover fillet, two or three nozzle rows uppermost can be covered targetedly.By promoting cover fillet downwards further, the one or more nozzle rows of width on the zone line of nozzle face or the intermediate altitude of nozzle face according to cover fillet can be covered.
Before cover fillet is placed at least one nozzle rows respectively in second or each other control position, thus the flow direction shrinking medium is diverted in this region.That is the nozzle of cover fillet not closely valve nozzles row, but the flow direction of contraction medium is turned in this region, thus make in the height of at least one cover fillet, do not shrink medium and directly impact on article or article assembly set.The contraction medium flowed out from nozzle clashes into cover fillet and turns to up or down thus, thus makes to shrink medium from room in the top and/or below inflow of cover fillet.
The vertical location of cover fillet can infinitely regulate to a great extent, and this is especially automatically and/or controllably via carrying out for vertical positioning element accordingly.Be set up as follows as an alternative, that is, the vertical position of at least one cover fillet can manually be conditioned.Other alternative scheme can realize the adjustment of cover fillet in so-called vertical grid with the step limited.
According to the embodiment that the present invention is other, compressive shrinkage machines comprises the parts for angular adjustment.At least one cover fillet can be conditioned relative to the angle of nozzle face thus.Usually be set up as follows, that is, cover fillet is arranged in the plane be parallel to a great extent perpendicular to the nozzle face of transport level.But also can be as follows favourable, that is, cover fillet and nozzle face are arranged to an angle limited, turn to targetedly so that the flow direction of realization contraction medium is only upwards or to a great extent only downward to a great extent.This can change according to the difference of article or article assembly set.
According to perpendicular to cover fillet the second length and to a great extent perpendicular to the cover fillet width of transporting direction, at least one, preferably two or three nozzle rows are covered by cover fillet.According to the preferred embodiment of the present invention, the center-to-center distance between the nozzle rows that cover fillet is at least adjacent with two is equally wide.Particularly preferably use so-called nozzle center spacing to add a nozzle diameter, the spacing that is between nozzle center's point and nozzle center's point of second nozzle of the first jet of adjacent column adds a nozzle diameter.It should be the spilling opening shrinking medium at this nozzle diameter.If have the cover fillet being roughly less than the width of the twice spacing of two adjacent nozzle rows corresponding to the width or have of one times of spacing to be positioned in center before nozzle rows, the contraction medium so flowed out from this nozzle rows can not flow directly on article or article assembly set.The substitute is, above cover fillet and/or the contraction medium of below flow in well along the flow direction of orientation up or down.But utilize the about twice the spacing cover fillet of the width of maximum about three times of spacing corresponding to two adjacent nozzle rows that have corresponding to two adjacent nozzle rows, two nozzle rows advantageously can be covered etc. when corresponding location.
The cover fillet that can regulate preferably has the width of 50mm to 100mm, thus in the OC situation of about 40mm of two adjacent nozzle rows, the contraction medium flowed out from maximum two to four nozzle rows of mutually arranging up and down can be covered simultaneously.
In addition, compressive shrinkage machines can comprise the parts for horizontal location cover fillet, thus the spacing between nozzle face and cover fillet can be modified.Spacing between nozzle face and cover fillet is less, and flow pressure is larger, utilizes this flow pressure above cover fillet and/or the contraction medium of below to flow in compressive shrinkage machines in room.
According to the other embodiment of the present invention, at least one nozzle face for the borehole wall is attached troops to a unit at least two movable cover fillets.This cover fillet preferably can not interdependently regulate, and this particularly relates to vertically location and/or angular adjustment and/or horizontal location.The contraction medium be transported to thus in two sensitizing ranges of article or article assembly set is covered or is turned to.Therefore the region of such as upper film clothing can be protected.Label area can be protected extraly, especially when thermal label etc.Lower film clothing region can be protected as an alternative.Especially there is following problem in this region, that is, press lower film clothing downwards by the contracting agent of usual orientation downwards.If the pressure produced by contracting agent is greater than the convergent force of film, the structure that shrink wrapping is intact so can be hindered.Have in the other embodiment of the compressive shrinkage machines of three movable cover fillets in each nozzle face, correspondingly three regions can by covering contracting agent stream to protect.Such as can protect upper film clothing region, label area and lower film region simultaneously.
Utilize cover fillet, the nozzle face of compressive shrinkage machines only one covered at least partly to several nozzle rows simultaneously.In particular due to cover fillet, nozzle is not closed.The substitute is, turn at least partly from by the contraction medium flowed out the nozzle that covers.That is, in this region, shrink medium and be not fed directly to on article or article assembly set in the interior room of compressive shrinkage machines, but only for indirectly heating, because it causes heat to be transported to further in the interior room of compressive shrinkage machines.Remain unchanged to a great extent in the heating power running state of compressive shrinkage machines inside thus.In addition, the specific region of nozzle face can be covered more neatly.In addition, cover fillet can at a certain angle relative to nozzle face setting, to produce favourable flow direction.In addition can be set up as follows, that is, each guide piece, especially on the guide piece upper seamed edge that is arranged in cover fillet and/or lower seamed edge, to affect from being covered and the flow direction of contraction medium that nozzle rows freely adjacent in addition flows out.Utilize according to cover fillet of the present invention, the flow graph in compressive shrinkage machines is matched with respective product at least partially better.In addition be favourable as follows, that is, the time of heat in passage remains unchanged, because only several nozzle is covered and the amount therefore not changing the contraction medium be transferred is necessary, to keep flowing velocity constant.
In addition be favourable as follows, that is, the compressive shrinkage machines with the borehole wall existed can install corresponding cover fillet additional.Therefore customer need not the new compressive shrinkage machines of compulsory purchase described functional to realize.
According to particularly preferred embodiment, cover fillet is made up of the load assembly with at least two cover tiles disposed thereon.Cover tile can such as directly be fixed on load assembly or such as be arranged at least two holding elements on load assembly.As an alternative, load assembly is provided with at least two for arranging the position units of cover tile.
According to embodiments of the present invention, load assembly has the second length, and it is roughly corresponding to the first length of the borehole wall, and that is load assembly extends along the whole borehole wall in the conveying direction at least to a great extent.Load assembly is especially configured to the framework junction part of pectination.First frame element forms so-called comb back.The length of the first frame element corresponding to load assembly the second length and therefore roughly corresponding to the first length of the borehole wall.First frame element is built as follows, that is, shrink medium and flow in the interior room of compressive shrinkage machines through the first frame element to a great extent unblockedly.First frame element such as can have longitudinal tie rod of the second length by least two, these two longitudinal tie rods are interconnected by the lateral tie connected and are mutually stablized.
First frame element is furnished with the first holding element, and it forms so-called comb.Holding element is such as attached troops to a unit in stable lateral tie.Preferably cover tile can be arranged between two holding elements or be arranged on every two holding elements.Such as can be set up as follows, that is, the first holding element is simultaneously for keeping two adjacent cover tiles, thus in order to keep two cover tiles to be such as provided with three the first holding elements, is correspondingly provided with four first holding elements etc. to keep three cover tiles.Extraly, other the second holding element can be arranged for extra maintenance and/or stable cover tile.
According to embodiments of the present invention, at least two cover tiles can be arranged on load assembly in the conveying direction with in succession following.Preferably, load assembly is divided into multiple by the layout of holding member, especially five or six position units for cover tile, thus makes cover fillet can in succession follow by maximum five or six the cover tile that arow is arranged on load assembly to form.Cover tile has the 3rd length in the conveying direction respectively.The summation being arranged in the 3rd length of the cover tile on load assembly is less than or equal to the second length of load assembly, is less than or equal to the first length of the borehole wall in other words.
According to the difference of the effect expected, cover tile can differently design.Preferably at least two heteroid cover tiles are arranged on load assembly.In the simplest embodiment, cover tile is simple sheet material and is used as so-called shock sheet.Turn to up or down on shock sheet from by the contraction media impingement that flows out the nozzle rows that covers, thus make clashing into the contraction medium above or below sheet and to flow in compressive shrinkage machines in room and can not directly impact in this region on article or article assembly set.
The other embodiment of special cover tile can be designed as so-called to concentrate watt, segmentation watt or directed watt, and utilizing their to shrink MEDIA FLOW can be concentrated, segmentation and/or directed.In simple embodiment such as, for the upper seamed edge of cover tile and/or lower seamed edge are attached troops to a unit guide piece, guide piece.This guide piece will to be directed in compressive shrinkage machines in room owing to striking contraction MEDIA FLOW that cover tile turns to targetedly along specific direction.According to other embodiment, the width of cover tile is selected as follows, that is, utilize this width to cover multiple nozzle rows simultaneously.The special other embodiment to concentrate watt can comprise the more big uncork of smaller amounts, and via these openings, the contraction medium assembled from multiple nozzle rows intensively to flow in compressive shrinkage machines room.Opening can extra orientation ground structure or comprise extra guide piece, such as guide piece or analogue, thus the contraction medium concentrated to flow in compressive shrinkage machines room with concentrating watt orientation from special.
Other special cover tiles are configured to have for splitting and/or the segmentation watt of parts of directional retraction MEDIA FLOW or directed watt.The width of such as this special segmentation watt or directed watt is selected as follows, that is, utilize the nozzle of this width only nozzle rows to be capped.Segmentation watt or directed watt self have multiple less opening, shrink medium therefore can be sprayed in compressive shrinkage machines in room by thinner Ground Split through this opening.In addition, the direction of tiny contraction MEDIA FLOW can be regulated targetedly by suitable guide piece.
The use with the cover fillet of multiple cover tile allows the exact matching of pinch condition along transport section in compressive shrinkage machines.Can be arranged on load assembly according to the heteroid cover tile of embodiments of the present invention.In particular, heteroid cover tile, especially clashes into sheet, to concentrate watt, segmentation watt or directed watt, can be used as described above, wherein, at least one cover tile is the shock sheet simply clashing into sheet or have extra top and/or lower guide.When being that is arranged on load assembly by n cover tile, at least one cover tile clashes into sheet, prevents contracting agent from directly impacting on article or article assembly set thus at least in this region.Clash in the region of sheet cover tile at least one, the flow direction flowing into the contraction medium in compressive shrinkage machines in room is diverted, thus makes above cover fillet and/or the contraction medium of below to flow in compressive shrinkage machines in room.N-1 remaining cover tile freely can choose according to the difference of the requirement of processed article/article assembly set from above-described scheme.
In addition, the cover tile of different in width can be used, so that difference according to demand covers more or less nozzle rows along transport section in a particular area.Be set up as follows according to embodiment, that is, all position units on load assembly are equipped with cover tile, and wherein, at least one cover tile is the shock sheet simply clashing into sheet or have extra top and/or lower guide.But the working condition according to expecting also can be set up as follows, that is, independent position units does not equip cover tile.Therefore, in position units region freely, medium clear is shunk unimpededly and flow into unchangeably in the interior room of compressive shrinkage machines.Therefore cover fillet effectively cover corresponding the 3rd length lacked that length reduces lacked cover tile.
If shrinkable film is retracted as packaging with surrounding article assembly set in compressive shrinkage machines, so first shrinkable film is wrapped in blister-pack equipment, with surrounding article assembly set.In side direction, so-called film eye stays open.Wrapped article assembly set is transported as follows along the transport section in compressive shrinkage machines, that is, film eye is arranged in and is parallel in the plane of the borehole wall.The axis of film eye is correspondingly arranged perpendicular to the borehole wall.In contraction process, shrink medium is transfused between article via film eye, and shrinkable film is heated from inside thus.Be favourable as follows in the beginning region of compressive shrinkage machines, that is, the upper film clothing of package is stablized via film eye or is upwards turned to, and the film eye of side direction keeps maximally opening and shrinking medium and can be input to article sufficiently thus.Be favourable as follows based on this reason, that is, there is no the contraction media impingement of downward orientation in this region on upper film clothing.By using the cover tile of simple shock sheet form, this can be prevented from effectively.If use the cover tile with the guide piece making contraction medium upwards turn to targetedly in this region contrary, so upper film clothing can stay open targetedly.Be supposed to as follows in the end regions in the transport section of compressive shrinkage machines on the contrary, that is, film now due to its shrinkage character is pulled together and the portion film-coating of connecting also retracted downward on article.This such as can by arranging that the cover tile utilizing suitable guide piece to make contraction medium turn to targetedly realizes downwards in this region.Concentrated sheet or the cutting plate of both can be the shock sheet with lower guide this its also can the be guide piece with downward orientation.
In order to can make cover fillet simply when changing and be matched with other products rapidly, be set up as follows in addition, that is, cover tile is alternatively arranged when not needing interpolation instrument or other accessory and/or is fixed on load assembly.Holding element can such as be configured to following receiving element, cover tile can be pushed in this receiving element and by bolt, rivet be fixedly unnecessary, that is cover tile can be fixed on load assembly via receiving element discretely.
According to the embodiment that the present invention is other, cover tile is fixed on load assembly respectively movingly, and wherein, especially cover tile can individually be conditioned relative to the angle of load assembly.Preferably, the angle of each cover tile be arranged on load assembly does not rely on other respectively and is conditioned with being arranged in cover tile on load assembly.
Utilize according to cover fillet of the present invention, one is at least covered local to several nozzle rows simultaneously, wherein, the structure according to cover fillet be preferred embodiment made up of load assembly and cover tile can realize in the inner single coupling along the pinch condition in the region in transport section of compressive shrinkage machines.Because nozzle is not closed by the cover tile of cover fillet, but the contraction medium flowed out only is diverted, so remain unchanged to a great extent in the heating power running state of compressive shrinkage machines inside.In addition, the direction of the contraction medium flowed in the interior room of compressive shrinkage machines can regulate more neatly in the specific region of nozzle face.Utilize one of them cover fillet with cover tile, the flow graph in compressive shrinkage machines can be matched with respective product better.In addition be favourable as follows, that is, the time of heat in passage remains unchanged, because only several nozzle is covered and the amount therefore not changing the contraction medium be transferred is necessary, so that the flowing velocity of the medium that remains retracted is constant targetedly.
In addition be favourable as follows, that is, the compressive shrinkage machines with the borehole wall existed can install the cover fillet accordingly with cover tile additional.Therefore customer need not the new compressive shrinkage machines of compulsory purchase described functional to realize.
In addition the present invention relates to one and will surround the method for the film shrink of article or article assembly set in (as described above) compressive shrinkage machines.At least one independent nozzle rows of at least one nozzle face is covered at least partly in the method, thus makes turned in the region of nozzle rows that covers from by the contraction medium that flows into the nozzle of nozzle rows that covers in compressive shrinkage machines in room and directly do not impacting on article or article assembly set.In particular, by least one can vertical motion, be placed in nozzle face before cover fillet be positioned at corresponding nozzle rows before, at least one nozzle rows is covered, and the second length of this cover fillet is to a great extent corresponding to the first length of the borehole wall.
