Technical field
The present invention relates to compressive shrinkage machines and method that a kind of film thermal for surrounding article or article assembly set shrinks.
Background technology
With article, especially during bundled of the packing such as drinking container, bottle, article make up and wrap shrinkable film in the mode of expectation.Shrinkable film by being retracted with carrying the besieged article of hot air in constricted channel.Air loading by blast tube, nozzle pipe and the borehole wall is known in the prior art.
The bundle part is processed along the track of a plurality of parallel transmission in constricted channel usually according to their size.On all sides that hot air can be loaded into all bundle parts, must also be provided with such as lower member bringing hot air into, these parts will be injected between the article of parallel transmission as the hot air that shrinks medium.For example many rails are processed, the constricted channel with at least one middle borehole wall is used.The inner borehole wall all has nozzle opening on two side wall surfaces, thereby hot air flows out to the inside of constricted channel from two sides.
The borehole wall commonly known in the art is the wall with internal cavities, and hot air is blown in this cavity.The borehole wall has respectively at least one air that preferably is arranged in the upper area and enters opening for this reason, enters the opening hot air by this air and is blown into the borehole wall from the top and passes subsequently the inside that nozzle opening flows to constricted channel.
Article or bundle part typically have different sensitizing ranges.Following based on this reason is favourable,, hot air is loaded into the little specific region of intensity that is.For example EP2319769A has described the borehole wall with a plurality of nozzles.These nozzle placement become row.Attach troops to a unit for each nozzle rows and to be useful on the amount of regulating thermal current and/or the parts of flowing angle.These parts comprise respectively the exchangeable nozzle sheet that can push in the holding element, and wherein, the exchangeable nozzle sheet especially can be parallel to borehole wall motion and be to replace.Constricted channel should be matched with the height of packed goods thus, so that the contraction quality that is improved thus.
In addition, by prior art is known adjustable nozzle face closure plate arranged, it can move from top to bottom and therefore begin one by one valve nozzles row from the top, in order to make constricted channel be matched with the height of packed goods.Sealed nozzle yet problem is, air is still less turned round in constricted channel inside, and the internal temperature in the passage descends thus.This has changed the heating power running state and has needed the again adjustment of cal val or like that.
Summary of the invention
Task of the present invention is to utilize in compressive shrinkage machines the contraction medium to realize loading best bundle part or article; thereby can protect targetedly the sensitizing range of bundle part or article; wherein, the heating power running state in the compressive shrinkage machines remains unaffected to a great extent.
Above-mentioned task solves by following compressive shrinkage machines and method, and this equipment and method comprise the feature of claim 1 and 15.Favourable design plan is described by dependent claims in addition.
The present invention relates to the compressive shrinkage machines that a kind of film thermal for surrounding article or article assembly set shrinks.Compressive shrinkage machines comprises that at least one has for the inner room in the transmission highway section of article or article assembly set and at least one and is used for will shrinking medium transport to the parts of the inner room of compressive shrinkage machines.Inner room comprises at least one, and preferred at least two have the first length and each at least one borehole wall towards the nozzle face of the inner room of compressive shrinkage machines.Nozzle face comprises a plurality of nozzles towards article or article assembly set orientation, and it is arranged to the nozzle rows of preferred parallel.By nozzle, shrink the medium streamwise and guide to the inner room from the borehole wall.
According to the present invention ground, be at least one nozzle face of the borehole wall at least one movable cover fillet of attaching troops to a unit.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, cover at least one at the first control position cover fillet so, the upper nozzle row of preferred at least two or at least three boreholes wall or nozzle face.If lower area only in the corresponding borehole wall, for example the bottom of side wall surface 80% is configured to nozzle face, and cover fillet can be arranged in above the nozzle face as follows in the first control position so, that is, do not have nozzle rows to be covered.
Can be pushed at least the second control position by the vertical motion cover fillet, before cover fillet places at least one nozzle rows in this second control position and with this nozzle rows separately.Cover fillet comprises at least one following subregion, and shrinking medium cannot see through in this subregion, thereby the flow direction that shrinks medium turns in this subregion.Especially directly impact on article or article assembly set not shrinking medium on the height of nozzle face, wherein, on the height of nozzle face, be furnished with now at least one cover fillet for shrinking at least one not penetrable subregion of medium.Spacing between nozzle face and the cover fillet is selected as follows, namely, shrinking medium can be from freely being overflowed by the nozzle rows that covers, however can bump against on the cover fillet and turn to up or down thus and therefore above cover fillet and/or below at least one subregion in flow into or import in the inner room of inner room.Spacing between preferred nozzle face and the cover fillet is 0.5 times of nozzle diameter at least.Therefore the Special Areas of article or article assembly set is protected and do not shunk flowing directly into of medium and affect targetedly in the subregion in transportation highway section at compressive shrinkage machines at least.
If shrinkable film is retracted as packing with surrounding the article assembly set in compressive shrinkage machines, so at first shrinkable film surrounds this article assembly set ground and is wrapped in thin-film package equipment.So-called film eye stays open on side direction.Along the transportation of the transportation highway section in compressive shrinkage machines, that is, the film eye is arranged in the plane that is parallel to the borehole wall wrapped article assembly set as follows.The axis of film eye is correspondingly arranged perpendicular to the borehole wall.The film eye is by upper film clothing and the restriction of lower film clothing.The upper film clothing should not pressed downwards in compressive shrinkage machines, because this has hindered the contraction medium to flow in the article assembly set via the film eye.The contraction medium that flows between the article of article assembly set is necessary, so that heat shrink film and obtain best contraction result internally.Following based on this reason is favourable, that is, being in the contraction MEDIA FLOW that flows out the nozzle rows of sustained height from least one and upper film clothing can be covered by cover fillet, because the upper film clothing can be stablized thus.
In the situation of the first embodiment, wherein whole side wall surface is configured to nozzle face, the second control position is 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 at 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 for example 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, uppermost two or three nozzle rows can be covered targetedly.By further downwards promoting cover fillet, can be covered according to the width of the cover fillet one or more nozzle rows on the intermediate altitude of the zone line of nozzle face or nozzle face.
Cover fillet second or each other control position in place respectively at least one nozzle rows before, thereby so that shrink the flow direction of medium and in this zone, be diverted.That is to say that cover fillet does not have the closely nozzle of valve nozzles row, but the flow direction that shrinks medium is turned in this zone, thereby so that in the height of at least one cover fillet, do not shrink the direct impact of medium on article or article assembly set.The contraction medium that flows out from nozzle clashes into cover fillet and turns to up or down thus, thereby so that shrinks medium from the top and/or below inflow inner room of cover fillet.
The vertical location of cover fillet can infinitely be regulated to a great extent, and this is automation ground and/or controllably be used for vertical positioning element and carry out via corresponding especially.Following being set up as an alternative, that is, the vertical position of at least one cover fillet can manually be conditioned.Other alternative scheme can realize the adjusting of cover fillet in so-called vertical grid with the step that limits.
According to the other embodiment of the present invention, compressive shrinkage machines comprises the parts for angular adjustment.At least one cover fillet can be conditioned with respect to the angle of nozzle face thus.Usually following being set up, that is, cover fillet is arranged in the plane that is parallel to a great extent perpendicular to the nozzle face on transportation plane.Yet following also can be favourable,, cover fillet and nozzle face is arranged to the angle of a restriction that is, turns to targetedly so that the flow direction of realizing shrinking 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 the second length of cover fillet 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, cover fillet at least with two adjacent nozzle rows between center-to-center distance the same wide.Particularly preferably use so-called nozzle center spacing to add a nozzle diameter, that is to say that the spacing between nozzle center's point of nozzle center's point of the first nozzle of adjacent column and second nozzle adds a nozzle diameter.Should be the opening that overflows that shrinks medium at this nozzle diameter.Be positioned in the center if having roughly corresponding to the width of one times of spacing or the cover fillet that has less than the width of the twice spacing of two adjacent nozzle rows before nozzle rows, the contraction medium that flows out from this nozzle rows so can not flow directly on article or the article assembly set.The substitute is, above cover fillet and/or below the contraction medium flow in the well along the flow direction of orientation up or down.Utilization has corresponding to about twice spacing of two adjacent nozzle rows but at most corresponding to the cover fillet of the width of about three times of spacings of two adjacent nozzle rows, two nozzle rows can advantageously be covered etc. in the situation of corresponding location.
The cover fillet that can regulate preferably has the width of 50mm to 100mm, thereby in the OC situation of about 40mm of two adjacent nozzle rows, the contraction medium that flows 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 the horizontal location cover fillet, thereby so that the spacing between nozzle face and the cover fillet can be modified.Spacing between nozzle face and the cover fillet is less, and flow pressure is just larger, utilize this flow pressure above cover fillet and/or below the contraction medium flow in the inner room of compressive shrinkage machines.
According to the other embodiment of the present invention, be at least one nozzle face of the borehole wall at least two movable cover fillets of attaching troops to a unit.This cover fillet preferably can interdependently not regulated, and this relates in particular to vertical location and/or angular adjustment and/or horizontal location.The contraction medium that is transported to thus in two sensitizing ranges of article or article assembly set is covered or is turned to.Therefore for example the zone of upper film clothing can be protected.Label area can be protected extraly, especially in the situation of thermal label etc.Lower film clothing zone can be protected as an alternative.Following problem is especially arranged in this zone, that is, downwards press lower film clothing by the contracting agent that usually is orientated downwards.If the pressure that produces by contracting agent can hinder the intact structure of shrink wrapping so greater than the convergent force of film.Have in the other embodiment of the compressive shrinkage machines of three movable cover fillets in each nozzle face, correspondingly Three regions can be protected by covering contracting agent stream.For example can protect simultaneously upper film clothing zone, label area and lower film zone.
Utilize cover fillet, the nozzle face of compressive shrinkage machines only one covered simultaneously at least partly to several nozzle rows.Owing to cover fillet, nozzle is not closed in particular.The substitute is, from being turned at least partly by the contraction medium that flows out the nozzle that covers.That is to say, in this zone, shrink in the inner room that medium is not fed directly to compressive shrinkage machines on article or article assembly set, but only be used for indirectly heating, because it causes heat further to be transported in the inner room of compressive shrinkage machines.Heating power running state in compressive shrinkage machines inside remains unchanged to a great extent thus.In addition, the specific region of nozzle face can be covered more neatly.In addition, cover fillet can be at a certain angle with respect to nozzle face by putting, in order to produce favourable flow direction.In addition following can being set up, that is, each guide piece, especially guide piece are arranged on the upper seamed edge and/or lower seamed edge of cover fillet, so that impact is from being covered and the in addition flow direction of the contraction medium that flows out of adjacent freely nozzle rows.Utilize according to cover fillet of the present invention, the flow graph in compressive shrinkage machines is matched with product separately at least partially better.Following in addition is favourable, that is, the time of heat in the passage remains unchanged, because only several nozzles are covered and the amount that therefore do not change the contraction medium that is transferred is necessary, in order to keep flowing velocity constant.
Following in addition is favourable, that is, the compressive shrinkage machines with borehole wall that has existed can install corresponding cover fillet additional.Therefore needn't the compulsory purchase new compressive shrinkage machines of customer is described functional to realize.
According to particularly preferred embodiment, cover fillet is made of the load assembly with at least two cover tiles disposed thereon.Cover tile can for example directly be fixed on the load assembly or for example be arranged at least two holding elements on the load assembly.As an alternative, be provided with at least two position units that are used for arranging cover tile at load assembly.
According to embodiments of the present invention, load assembly has the second length, and it that is to say that roughly corresponding to the first length of the borehole wall load assembly extends along the whole borehole wall at least to a great extent on transporting direction.Load assembly especially is configured to the framework junction part of pectination.The first frame element forms so-called comb back.The length of the first frame element is corresponding to the second length of load assembly and therefore roughly corresponding to the first length of the borehole wall.The first frame element is built as follows, that is, shrink medium and pass in the inner room that the first frame element flows into compressive shrinkage machines to a great extent unblockedly.The first frame element can be for example by at least two vertical tie rods with second length, and these two vertical tie rods interconnect by the lateral tie that connects and be mutually stable.
Be furnished with the first holding element at the first frame element, it forms so-called broach.Holding element is for example attached troops to a unit in stable lateral tie.Preferably cover tile can be arranged between two holding elements or be arranged on per two holding elements.Following can being set up for example, that is, the first holding element is used for keeping two adjacent cover tiles simultaneously, thereby in order to keep two cover tiles for example to be provided with three the first holding elements, correspondingly is provided with four first holding elements etc. in order 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 the load assembly on the transporting direction with in succession following.Preferably, the layout of load assembly by holding member is divided into a plurality of, especially five or six position units that are used for cover tile, thus so that cover fillet can be followed the cover tile that arow is arranged on the load assembly in succession by maximum five or six consists of.Cover tile has respectively the 3rd length on transporting direction.The summation that is arranged in the 3rd length of the cover tile on the load assembly is less than or equal to the second length of load assembly, is less than or equal in other words the first length of the borehole wall.
According to the difference of the effect of expecting, cover tile can differently design.Preferably at least two heteroid cover tiles are arranged on the load assembly.In the simplest embodiment, cover tile is simple sheet material and is used as so-called bump sheet.From being impacted by the contraction medium that is flowed out the nozzle rows that covers on the bump sheet and turn to up or down, thereby so that the contraction medium above or below the bump sheet flow in the inner room of compressive shrinkage machines and in this zone, can directly not impact on article or article assembly set.
The other embodiment of special cover tile can be designed as so-called concentrate watt, cuts apart watt or directed watt, utilizes their to shrink MEDIA FLOW and can be concentrated, and cuts apart and/or directed.In simple embodiment, be the upper seamed edge of cover tile and/or time seamed edge attach troops to a unit guide piece, for example guide piece.This guide piece will be directed in the inner room of compressive shrinkage machines along specific direction targetedly owing to striking the contraction MEDIA FLOW that turns on the cover tile.According to other embodiment, the width of cover tile is selected as follows, that is, utilize this width to cover simultaneously a plurality of nozzle rows.Special concentrated watt other embodiment can comprise the larger opening of smaller amounts, via these openings, flows into the inner room of compressive shrinkage machines from the contraction medium concentrated area that a plurality of nozzle rows are assembled.Opening can be additionally structure or comprise extra guide piece with being orientated, for example guide piece or analogue, thus the contraction medium of concentrating flows into the inner room of compressive shrinkage machines from the special watt orientation ground of concentrating.
Other special cover tiles are configured to have be used to cutting apart and/or the cutting apart watt or directed watt of the parts of directional retraction MEDIA FLOW.This special cut apart watt or directed watt width is selected as follows for example, that is, only the nozzle of a nozzle rows is capped to utilize this width.Cut apart watt or directed watt self have a plurality of less openings, pass this opening and shrink medium and therefore can be divided thinlyyer and cede territory to spray in the inner room of compressive shrinkage machines.In addition, the direction of tiny contraction MEDIA FLOW can be regulated targetedly by suitable guide piece.
Use with cover fillet of a plurality of cover tiles allows in compressive shrinkage machines along the exact matching of the pinch condition in transportation highway section.Can be arranged on the load assembly according to the heteroid cover tile of embodiments of the present invention.In particular, heteroid cover tile especially clashes into sheet, concentrates watt, cuts apart watt or directed watt, can be used as described in the above, wherein, at least one cover tile is the bump sheet that simply clashes into sheet or have extra top and/or lower guide.That is to say n cover tile is arranged in the situation on the load assembly that at least one cover tile is the bump sheet, prevent in this zone at least that thus contracting agent from directly impacting on article or article assembly set.In the zone of at least one bump sheet cover tile, the flow direction that flow into the contraction medium in the compressive shrinkage machines inner room is diverted, thereby so that above cover fillet and/or below the contraction medium flow in the inner room of compressive shrinkage machines.N-1 remaining cover tile can freely choose from above-described scheme according to the difference of the requirement of processed article/article assembly set.
In addition, the cover tile of different in width can be used, in order to cover more or less nozzle rows along the transportation highway section in the specific region that do not coexist according to demand.Be set up according to embodiment is following, that is, all position units on load assembly are equipped with cover tile, and wherein, at least one cover tile is the bump sheet that simply clashes into sheet or have extra top and/or lower guide.But can be set up according to the working condition of expectation is following, that is, independent position units is not equipped cover tile yet.Therefore in position units zone freely, shrink medium clear and flow in the inner room of compressive shrinkage machines unimpededly and unchangeably.Therefore cover fillet effectively covers corresponding the 3rd length that lacks that length has reduced the cover tile that lacks.
If shrinkable film is retracted as packing with surrounding the article assembly set in compressive shrinkage machines, so at first shrinkable film surrounds article assembly set ground and is wrapped in blister-pack equipment.So-called film eye stays open on side direction.Wrapped article assembly set betransported as follows along the transportation highway section in compressive shrinkage machines, that is, the film eye is arranged in the plane that is parallel to the borehole wall.The axis of film eye is correspondingly arranged perpendicular to the borehole wall.Shrink medium and be transfused between the article via the film eye in contraction process, shrinkable film is heated internally thus.Following in the beginning zone of compressive shrinkage machines is favourable, that is, the upper film clothing of package is stablized via the film eye or upwards turned to, and the film eye of side direction keeps opening the largelyst and shrinking medium being input to sufficiently article thus.Following based on this reason is favourable, that is, not having downwards in this zone, the contraction medium of orientation impacts on the upper film clothing.This can be prevented from cover tile by using simple bump sheet form effectively.If opposite in this zone, use to have make the cover tile that shrinks the guide piece that medium upwards turns to targetedly, the upper film clothing can stay open targetedly so.Opposite following being supposed in the end regions in the transportation highway section of compressive shrinkage machines, that is, film is now because its shrinkage character is pulled together and the section film-coating of connecting also is retracted on the article downwards.This cover tile that contraction medium is turned to is downwards targetedly realized.Both can be that the bump sheet with lower guide also can be concentrated sheet or the cutting plate with guide piece of downward orientation this its.
In order in the situation of conversion, can to make cover fillet simply and rapidly be matched with other products, in addition following being set up, that is, cover tile is replacedly arranged and/or is fixed on the load assembly in the situation that does not need interpolation instrument or other accessory.Holding element can for example be configured to following receiving element, cover tile can be pushed in this receiving element and by bolt, rivet fixedly be unnecessary, that is to say that cover tile can be fixed on the load assembly discretely via receiving element.
According to the other embodiment of the present invention, cover tile is fixed on respectively on the load assembly movingly, and wherein, especially cover tile can individually be conditioned with respect to the angle of load assembly.Preferably, each angle that is arranged in the cover tile on the load assembly does not rely on respectively other and is conditioned with being arranged in cover tile on the load assembly.
Utilize according to cover fillet of the present invention, one extremely the local at least while of several nozzle rows is covered, the structure of the foundation cover fillet preferred embodiment that wherein, is made of load assembly and cover tile can be implemented in the inner single coupling along the pinch condition in the zone in transportation highway section of compressive shrinkage machines.Because nozzle is by the cover tile of cover fillet sealing, but the contraction medium that flows 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 in the inner room of inflow compressive shrinkage machines can be regulated in the specific region of nozzle face more neatly.Utilization has one of them cover fillet of cover tile, and the flow graph in compressive shrinkage machines can be matched with product separately better.Following in addition is favourable, that is, the time of heat in the passage remains unchanged, because only several nozzles are covered and the amount that therefore do not change the contraction medium that is transferred is necessary targetedly, so that the flowing velocity of the medium that remains retracted is constant.
Following in addition is favourable, that is, the compressive shrinkage machines with borehole wall that has existed can install the cover fillet that has accordingly cover tile additional.Therefore needn't the compulsory purchase new compressive shrinkage machines of customer is described functional to realize.
The present invention relates in addition the method that a kind of film thermal that will surround article or article assembly set in (as described above) compressive shrinkage machines shrinks.At least one independent nozzle rows of at least one nozzle face is covered at least partly in the method, thereby so that the contraction medium from the inner room that is flowed into compressive shrinkage machines the nozzle of the nozzle rows that covered in the zone of the nozzle rows that is covered, turn to and directly do not impact on article or article assembly set.In particular, but by at least one vertical motion, place cover fillet before the nozzle face to be positioned at before the corresponding nozzle rows, at least one nozzle rows is covered, the second length of this cover fillet is to a great extent corresponding to the first length of the borehole wall.
