Description
Technical field
The present invention relates to method and a kind of shaping, filling and the sealing machine (FFS machine) of the package of the type that a kind of manufacturing forms by the single or multiple lift plate of material, and relate to a kind of package of on this FFS machine according to the present invention, producing.
Background technology
In the art, the FFS machine is widely used in and various goods, particularly food, candy and the relevant packing of many other objects.Basically, when being supplied to plate of material, FFS machine operation, along with plate is fed in the machine, the building mortion in the machine is by attached continuously each other and plate of material is configured as pipe fitting with the both sides of the edge of plate.The device that downstream in machine also is provided with the end seal portion that is used to form---being called as transverse sealing portion in the application---, make pipe be defined by longitudinal direction transverse to pipe fitting, afterwards, the pipe fitting that is defined like this is filled with object to be packaged and also is provided with end seal portion transverse to the longitudinal direction of pipe fitting.In this way, be dirt cheap, make things convenient for and the failure-free package with minimum cost formation.Plate of material is normally based on poly-mer, and can be provided with stamp so that will send the user to about the information of the object in the package.
The package of these types is well-known and by the daily use of most of customer in the art.Being used for the various machines of production process and the example of embodiment discloses in WO 03045816, US2007269146, EP176908, EP1746043, EP1026077, WO 2007/106916, JP10305806, WO 2004002835 and many other approach.
The example of method of making this package is from US 5,337, and is known in 539.According to disclosed method, the material batten is configured as V-arrangement or flute profile.Three different embodiments are disclosed in this stage.In the first embodiment, form transverse sealing portion, promptly the sidepiece of batten is combined together to form pocket, waits to be placed to material or article in the pocket to this pocket filling afterwards.In second embodiment, material or article are placed in the bottom of V-arrangement on the batten or groove, and the free lateral edges of batten is engaged/seals to form pipe fitting afterwards.At last, transverse sealing portion defines out the next package of each package and formation.In the 3rd embodiment, described pipe fitting is shaped around the VFF filling tube, and feasible described pipe fitting and transverse sealing portion in conjunction with batten lateral edges formation sealing together forms, under these circumstances, pipe fitting will upwards be opened with respect to filling tube, and be limited by transverse sealing portion downwards.This document does not provide any device of making package be easy to open of being used to.
The problem that the well-known package of this class is produced is the situation of customer or the necessary open package of user.Usually, vertical connection between the both sides of the edge of material bottom is welded together to form flank sheet (flap), and form the nature point at this flank sheet with the end seal portion place of coincidence, the customer will attempt the open package at described natural some place, so that obtain to lead to the in-to-in inlet.Sealing is usually by being welded together to form polymeric material, make in end seal portion and flank sheet, all to form more firm being connected, when attempting open package, need sizable power to make in opening procedure the peelable package of user and pour out contents.
In this, attempted designing weld part to obtain desired tensile force.This requires surface together to be welded to have certain characteristic to allow welding/welding again.For example, the paper tinsel that is used to twine/pack the article such as candy has multilayer usually.Usually, be printed on it picture, literal etc. the layer cover by thin protective layer.Layer thickness is usually in the scope of 5-60 μ, and whole paper tinsel (thickness) is the summation of different layers thickness.Can increase such as being other layers such as unidirectional layer of tearing and/or barrier layer.These layers all present different characteristics and the paper tinsel with desired characteristic is provided jointly, and are identical for welding/welding situation.When the multilayer paper tinsel of these types is used for FFS machine (horizontal and vertical two kinds), these paper tinsels normally must with the inboard outside that combines.These aspects are disclosed among the US5826985.Therefore, except that having desired quality (barrier, stamp etc.), paper tinsel also should weld mutually/welding.
For fear of this situation, different solutions has been proposed.One of this solution provides the little otch by all material layer, described otch is arranged in the end seal portion along the longitudinal direction, but only limit to make this otch to enter in the sealing of end several millimeters, tear section start, the bight that for example can more easily tear package thus thereby form.Referring to the various examples among JP 10250764, JP 2003191965, WO 9216431 and the JP2004182267.In some of these examples, by further be provided for opening along it, partly pass the paper tinsel layer, the tearing line or provide band to make that this band can tear paper tinsel when band is pullled and help tear action of form of cut or cuts referring to for example JP 10250764.This forms more limited opening again under most of situation, and in some cases, depend on mode of tearing the bight and the material of making package, can form the situation of destroying package in the mode identical, referring to for example US 5826985 with mode described above.
In case this something in common of opening of two types is that package has just been torn and can not reseals package under the situation that whole contents are not used.
Based on these purposes, multiple solution has been proposed, for example, be incorporated near the end seal portion the material by zip-tie with resealable.But, even this is than expensive process and requires the size of package still to keep constant relatively after a part of contents have been removed.
Summary of the invention
The purpose of this invention is to provide a kind of method, equipment and package, described method, equipment and package have reduced problem above-mentioned, and other advantage cheapness, the failure-free mode that opening is provided in the package that relates in particular to the type of mentioning in the above is provided, wherein can needn't have used so energetically so that the user faces under the situation of the risk of destroying whole package in (open package) process and opens this package.
The present invention realizes this purpose by the method for the package of the type that a kind of manufacturing is provided is formed by the single or multiple lift plate of material, wherein said package has the feature that is easy to open, this plate forms the finished product package, the inboard that this finished product packing spare has the outside and is fit to contact with thing to be packaged, described method comprises the following steps:
-make plate be configured as pipe fitting by the both sides of the edge of end wise connecting panel;
Form the flank sheet on the-wherein said outside that is connected this pipe fitting, perhaps make pipe fitting through having projection fin (fin) thus building mortion on the outside of pipe fitting, form the flank sheet;
-wherein transverse sealing portion is set across pipe fitting, thus between two transverse sealing portions, define each package;
-in described transverse sealing portion or between described transverse sealing portion, set up perforation line, be used to make two adjacent packages separate/separately;
-adjacent side fin or fin are set up one or more layers a perforation plate or that form this plate, this perforation is extended and is parallel to flank sheet or fin or becomes to be no more than 60 ° angle with respect to flank sheet or fin from perforation line, and extends or extend in the transverse sealing portion towards transverse sealing portion.
At first, should be noted that the packing stage of not considering package, because it depends on that the manufacturing that product is caused the machine in such package during the process that forms package is well-known in the art.The present invention only relates to the novel feature that is provided for opening the finished product package with to be used for the device type of filling and packing spare irrelevant.
This point especially realizes by last step, i.e. near the perforation of the layer of material layer the flank sheet.Perforation is parallel to the flank sheet and extends a bit of distance or extend to the transverse sealing portion towards transverse sealing portion from the edge of perforation line, make and to hold package when also pullling the flank sheet in edge with one as the user with the another hand, perforation will provide the meeting weak part that atarting material is torn, thereby make material be torn and can obtain to lead to the inlet of interior at an easy rate under the situation of not damaging described package.Reperformance test clearly illustrates that perforation provides opening easily of package, and described opening well limited and be limited in desired package part.
Only perforation obviously is different from the solution that proposes above to the layer of material layer, in the above in the solution of Ti Chuing, the otch that passes all material layer in the transverse sealing portion has the perforation of passing the material layer in the transverse sealing portion, make that the packing on the package both sides are torn simultaneously, thereby have the risk of damaging package fully.By being limited to, perforation only penetrates the layer of material layer, user's tearing action and will in package, form and relatively simplify the tearing notch of (clean) and can not damage package fully on the flank sheet.
In the art, make between the mode of such package and have difference.If, then be called vertical shaping, filling and sealing machine when vertical position forms when package inserts contents in the package.When contents are guided by on even keel, then be called horizontal shaping, filling and sealing machine.Based on purpose of the present invention, this machine of two types all can use, and has identical effect.
In addition, the mode of making sealing during sheet material/panel material forms package has two kinds of main types: bridging type sealing and finned sealing.Bridging type sealing by simply with a plate bracing on another piece plate and connect this two boards by welding, gluing or alternate manner and form.By this way, the neither homonymy of plate is joined together and becomes the inboard of package and the outside of package respectively.When using finned sealing, the inboard, both sides of plate forms fin or fin thus to connecting medially.Within the scope of the invention, sealing means is to not influence of the present invention, as long as fin or fin can be provided., can predict for this reason, use bridging type sealing or the finned position of not expecting open package that is sealed in to form generator under the situation of fin/fin.Fin can form by forming tool, and perhaps can be used as the separate part that is adhered to or be welded on the pipe fitting outside provides.
In this respect, the implication of statement of understanding " single or multiple lift plate of material " is also very important.In the art, referring to for example US5826985, generally use the plate of being made up of a plurality of different layers, every layer has its distinctive characteristic, makes formed production board have the particular characteristics of the purpose of being used to specify.The layer that only being exemplified as of these layers that can mention can be torn along a direction, has the specific coatings such as metal so that this layer has airtight/not layer, UV protective cover, barrier etc. of vapour transmission.The composition of plate has no importance for the present invention, but in some embodiments of the present invention, needs the composition of plate can be enough to realize desired effect, and promptly described perforation extends through some material layers of forming sheet material.
Particularly when the material layer that contains PE, CPP or PP was used in combination with laser, importantly recognizing only needed some layers are bored a hole.This is because for these materials of laser beam cutting, requires high-octane relatively laser, and other sheet material of laser beam cutting then requires much lower laser energy.Identical aforesaid when tearing effect when realizing, owing to the reason of energy consumption, laser cost aspect and lower, only advantageously the layer that does not need high intensity laser beam is bored a hole when enough energy being sent to PE, CPP and PP material speed of production so that these materials are bored a hole.
According to plate structure perforation is positioned---promptly from parallel with fin to become with fin up to and comprise 60 ° of angles---to help to realize desired effect.This is because when by pullling fin perforation being torn, and boring a hole forms guiding crack towards fin, thus the structure that this fin is soldered and constituent ratio sheet material is more firm.When crack and fin meet, even when meet in 60 ° of angles, the crack also will form along fin, thereby desired invention effect is provided.
In having another favourable embodiment of novelty and creationary method, the perforation of the layer of plate bed of material is made in any one following:
-unsealing the part of a sheet material of projection between transverse sealing portion and the perforation line that two adjacent packages are separated;
-or in the part of this unsealing partial sum transverse sealing portion;
-or under the situation of the perforation line between two adjacent packages of the next-door neighbour of transverse sealing portion, only in transverse sealing portion.
By perforation being limited in the transverse sealing portion that is arranged in, free plate end or their combination, thereby it is still sealed and be not exposed in the environment to hold the volume of the goods in the package.
In another favourable embodiment, plate of material is the polymeric material flitch, wherein forms sealing and connecting portion by thermal welding or welding.Polymeric material is the most frequently used material type that is used for most of packages of being made by sheet material.Thermal welding or welding can provide reliable and firm sealing, and feasible selection according to sheet material provides good, firm package naturally, but weld zone is more firm than sheet material itself usually.
In another favourable embodiment, propose to substitute sheet material, wherein said material is nonweldable or material that can not thermal welding, sealing and connecting portion are by treating that coating adhesive forms to form sealing between the material surface of combination, and described material is selected from one or more in the following material: apply or uncoated cellulosic-based material, thin polymer film, aluminium base.In this, for example using, paper board material is known, on the side of described paper board material, promptly be used for a side that product to be packaged contacts on be provided with polymeric coating, make and to form sealing by welding in theory, but because the character of whole sheet material (being paper) needs to use adhesives to form sealing.
When using this process in so-called vertical FFS machine for example, sheet material is configured as pipe fitting around pipeline or building mortion, and this pipeline is used for material to be packaged is filled in the package simultaneously.Here, the edge segments of plate of material is by bracing, and soldered or glued together according to the type of sheet material, and wherein filling pipeline can be used as platform (land), promptly as the back support of weld wheel.In these cases, do not form the flank sheet, therefore in another favourable embodiment of the present invention, be provided with two rollers, make by through above fin in the alternate embodiments mentioned when forming the flank sheet, described flank sheet be heated or bear by on the either side that is arranged in the flank sheet and towards two heat that roller applied and/or pressure of described flank sheet bias voltage.Thereby form the flank sheet by this way, although the tradition manufacturing of such package does not need the side fin, but because according to the favourable deployment method that combines with perforation of the present invention, it is desirable that the flank sheet is set, and therefore the fin that matches with the side roller need be set on filling pipeline.
Provide perforating tool to form perforation, wherein this perforating tool can be selected from one or more in the following tool:
-cutter or the rotary cutter controlled according to speed of production, wherein cutter head has a plurality of cut edges that are spaced of matching with platform, this platform is positioned to make material through between cutter and the platform, activates cutter thus and set up perforation during cutting with in the contacted material of described platform;
-laser equipment;
-according to desired package size with respect to the position that is arranged on the mark positional punch on the sheet material, wherein be provided with and be used to detect described mark and use this information device as the input that is used to activate perforating tool.
In this respect, it is essential, only the layer of material layer is cut and makes the easy and failure-free can realize package under the situation of not damaging package tear as mentioned above, therefore platform be arranged to cutter platform is positioned at the material back with matching and the cutter positioning at opposite side, make that platform will stop cutter further to enter material when tool operating.
Using laser equipment cutting or engraving perforation is well-known technology.Well known in the artly be, can operate laser make they only penetrable material necessarily, very little distance.This can be by providing coating further to strengthen on the inboard of material, make laser equipment will detect different material behaviors, thereby and the penetration depth of laser is limited to this specified material layer, can only bore a hole at transverse sealing portion place very effectively thus to one deck of packing.
In order with higher production perforation to be positioned in the transverse sealing portion, packing are typically provided with the sign that is present on each package, for example bar code, stamp, typographic(al) mark etc.These marks can be used as be used for for example photronic check point with will to through the identification of photronic mark with the input of doing perforating tool, this perforating tool can be arranged in the photoemissive element downstream and activated in response to the detection of mark.By this way, can be further with in some cases Already in the very proven technique in the machine with the input of doing perforating tool, thereby provide perforation with respect to strapping wires in accurate, correct position.
In order to carry out according to creative method of the present invention, the invention also discloses a kind of shaping that is used to form package, filling and sealing machine, wherein said machine comprises and being used for the device of continuous sheet material transmission by machine, and described machine comprises the device that is used for forming at least one flank sheet on package, described machine also comprises device that is used to set up the leak free transverse area that extends substantially transversely to the extension of flank sheet and the device that is used to set up strapping wires, described strapping wires are built up in the described transverse area, wherein the leak free transverse area has two layers of material layer thickness at least, it is characterized in that, this machine comprises perforating tool, this perforating tool is close to and is parallel to described flank sheet bores a hole to the one deck in the two layers of material, this perforation is extended in described leak free transverse area, and this perforation extends to strapping wires at least.
Though the present invention will be described at the so-called formula production method of getting lines crossed, the present invention also is applicable to batch production.
Tandem is meant at one end discharges the finished product packing spare that accommodates goods to be packaged with Wrapping material supply in packaging machine and at the other end.This yes reasonable and feasible purposes of the present invention.But the present invention also is applicable to and makes portions of packaging material form the finished product package, for example stays an end and open.After this, in follow-up phase even in the another location, this package is filled with goods to be packaged and sealed.

The specific embodiment
Thereby Fig. 1 to Fig. 5 illustrates and being provided with perforation and having various examples according to the package of the feature that is easy to open of the present invention.
In Fig. 1, has its most basic configuration with the package shown in the label 1 generally.Plate of material 2 has formed package 1, and this package is defined by transverse sealing portion 3,4 at its arbitrary end.With reference to Fig. 7 and Figure 10, the qualification of the general direction of transverse sealing portion and package is determined according to the mode of Production and Packaging part.
As conspicuous from Fig. 7 and Figure 10 institute, package by theory unlimited long/for no reason plate of material 1 forms, described plate of material is configured as pipe fitting by means of the building mortion (not shown).This pipe fitting for example by near the sheet material weld together two edges 5,6 of sheet material is formed, also forms flank sheet 10 thereby form pipe fitting, referring to Fig. 1 simultaneously.
After forming flank sheet 10, this pipe fitting is by 3,4 sealings of transverse sealing portion, to form the space that is limited by formed pipe fitting and transverse sealing portion 3,4.
For open package easily, be provided with perforation or otch 7.In the embodiment shown in fig. 1, be provided with perforation 7 at the two ends of flank sheet 10, but can realize identical advantage by only a perforation 7 being set at arbitrary end of flank sheet.
Fig. 4 illustrates the situation that the bight 11 of flank sheet 10 has been raised with respect to package, thereby the tearing notches 8 that caused by perforation 7 can be opened package easily and basically point-blank.
Remained intact harmlessly by the lower material layer shown in the Reference numeral 12, and only top materials plate 13 breaks.
In the embodiment shown in fig. 1, the package of these types is made on so-called horizontal shaping, filling and sealing (FFS) machine usually, and package 9 shown in Figure 2 is made on vertical FFS machine usually, wherein edge 5 ', 6 ' interlaps and forms and connects sealing 20, and making does not provide flank sheet 10 when plate of material 2 forms pipe fitting.In this case, can provide the flank sheet as Fig. 8 and flank sheet building mortion shown in Figure 9 by installing.
Fig. 8 shows shaping/filling pipeline 14.The plate of material (not shown) also has been provided with connection sealing 20 (referring to Fig. 2) around described shaped pipe this moment, makes that the plate of material in this stage becomes tubulose.This pipe fitting is arranged in shaping/filling pipeline 14 outsides, and along with pipe fitting is advanced downwards in Fig. 8, this pipe fitting will engage with fin 15, thereby form gauffer in sheet material.Along with described material is further advanced, this gauffer will be extruded between two rollers 16,17 that are biased toward one another.Depend on the material type that is used for forming package, thereby can be by before the tight downstream of fin 15 and roller 16,17, adhesive spray nozzles being set so that roller presses together gauffer and the inside that scribbles adhesives of plate of material (being configured as pipe fitting here) pressed together seal gauffer, thereby form flank sheet 10.Perhaps, be suitable under the soldered situation at sheet material, roller 16,17 can be the welding roller, makes by heated rollers gauffer to be fused together in welding process, thereby forms flank sheet 10.
With reference to Fig. 2, flank sheet 10 accurately is set accordingly and bores a hole 7 with the described embodiment of Fig. 1.
Fig. 3 illustrates the embodiment that combines different technologies.Transverse sealing portion 3,4 makes in the identical mode of mode that is adopted with the foregoing description, and this 6 is described further with reference to the accompanying drawings, and is provided with longitudinal sealing portion 18 in addition with adjoining edge 5 ", 6 ", thereby form packages sealed part 2.By this way, so far the embodiment with shown in Figure 1 is corresponding fully for embodiment shown in Figure 3.
But, in some cases, expectation can be positioned at longitudinal sealing portion 18 position that is independent of the expectation open package, therefore the flank sheet 10 that is described with reference to Fig. 2 of manufacturing is arranged on diverse location, wherein flank sheet 10 is arranged near the perforation 7, thereby the feature that is easy to tear of such package is provided, and this feature has novelty and creativeness.Based on practical purpose, sealing 18 further can be fastened on the surface of packing and be fastened in the transverse sealing portion 3,4, make the user can not attempt mistakenly by on edge seal 18, pullling and open package.
Fig. 5 shows another embodiment of the present invention, wherein by tearing and package is opened at flank sheet 10 places, thereby provides the inlet that leads to interior.Perforation 7 has been separated, make a chadless on flank sheet 10 and a chadless 7 package originally on one's body.This package also is provided with resealing bar 20, and this resealing bar is arranged in now and is the position of flank sheet bottom and parallel with longitudinal direction 50 (referring to Fig. 1).By making the anterior bracing of flank sheet 10 and package 19, the sealing 20 of resealable can be pressed against on the surface 19 resealing package, thereby the residue contents of package are remained in the package.
Can select to be used for the material type of the sealing 20 of resealable as the case may be, described particular case depends on the quality of the resealing characteristic that sheet material and expectation realize.Sealing 20 can be selected from so-called peelable material or can only be double-faced adhesive tape etc., as long as it satisfies the requirement that can depress flank sheet 10 with respect to the surface 19 of package.
