The state of the art
Known by coil packing material production fluid in a next life body or the packing that can pour into food, which floor lamination coating this packing include, paper for example, and its two sides is coated with thermoplastic material, for example polyethylene.Packing may also include one deck barrier material with the one side of Food Contact in the packing, for example scribble the aluminium foil of thermoplastic material.In order to produce the packing of mentioned kind, be the wrapping machine feed by packing of rolling up the sheet form of pointing out above.Preferably by applying chemosterilant, for example superoxol carries out disinfection to packing in wrapping machine.During disinfecting steps, bactericidal agent also passes through at last, for example the method for heating vaporization and removing from the surface of packing.
Sterile packing are made the pipe of longitudinal sealing then.With sterile this pipe of food filling that pours into.In general, the example about such poured into food for example has fruit juice, sterile or milk, wine, catsup, vanilla sauce or full-bodied food etc. that high-temperature treatment (UHT) is crossed.Filling the pipe of food then between one or more pairs of circulation link chains that carry sealing mechanism or traverse member, pass through, specifically be on of a pair of band chain, the heat seal clamping plate to be arranged, and have opposed Sealing jaw, sealing mechanism interval rule ground wherein to clamp on another band chain and the sealing pipe.The band of resulting sealing and packing material is cutting between filling and the packages sealed then continuously, thereby provides the packing of many separation.
Known have various packings, a for example parallel tubular package.Be called as Tetra Brik
TMThe packing that comes to this.Another known package is so-called Tetra Prisma
TM, this is the parallel tubular package that has the inclined-plane.Be provided with two circulation link chain conveyers in order to produce such packing, they are equipped with Sealing jaw and opposed Sealing jaw respectively.These two circulation link chains define corresponding circulating path, they toward each other and parallel to each other, the pipe of packing is just supplied with between them.The corresponding opposed pressure sealing clamping plate that move back and forth on (heat seal) clamping plate on circulation link chain and another circulation link chain cooperate, so that spacing is clamping tube and make pipe sealing regularly, horizontal sealing so just is provided, thereby the packing of generation pillow shape, it may then, for example, by the folding finished form of making, yet this and the present invention are incoherent.
Packing with four sides shape, for example, Tetra Classic
TMOr TetraClassic
TMAseptic also is known.Therefore two pairs of circulation begin chain conveyers are just arranged.Each all is made up of a circulation link chain that carries (heat) Sealing jaw and another circulation link chain that carries opposed Sealing jaw conveyer, therefore in clamping and seal operation, clamping and seal operation are back and forth to be carried out by the clamping plate on the respective cycle chain, so just make following the leak free material bands of expanding subsequently in the first leak free material bands back of first direction expansion on the direction vertical with first direction.Produced packing in this way with four sides shape.
Packing normally are printed on a series of equally spaced same patterns in advance in one side, and these patterns will be on those parts that form the packing outside face at last.The thin slice of packing also can have, for example, and the corner of sipper pore, perforation or perforation etc.In this application, all pattern, sipper pore, perforation etc. are expressed as service unit, and this all is to be user or producer's service because of them in any case.For these service units common be, should to be packaged into another packing from one be unmodified in their position on the packing that processes, that is to say, the thin slice of packing must be located exactly, so that guarantee typographic pattern and sipper pore and/or shedding motion, the corner portions located of for example boring a hole is correctly located on the packing that processes.Yet the pipe that be difficult to guarantee packing is supplied with like this, makes packing be formed by this way, sealing and cutting at last, and promptly pattern etc. is all correctly located.During operation since packing be subjected to mechanically deform, heat effect, formed pipe filling product etc., so packing may be out of shape.Also may change in preprinted operating period (or forming perforation etc. during).
Known example as the relevant wrapping machine pointed out above is the wrapping machine that is called as TBA/19 and TBA/21, this wrapping machine can obtain from the Tetra Brik Packaging System of Modena, ITA city (Modena) Via Delfini1 there, and it is that to be used to make known registered trade mark (RTM) be Tetra Brik
TMThe packing of parallel tubular type, or known registered trade mark (RTM) is TetraPrisma
TMThe parallel tubular package that has the oblique angle.In these known package machines, used the automated pattern corrective system, this system has the sheet folding alive on some Sealing jaws that are connected to this wrapping machine, so that during operation, spurs more or less within the formation and sealing element that material enters wrapping machine.In EP-A-887 265 and the italian patent 1 296 062 authorized on June 9th, 1999, such device has been described.Yet this solution is quite complicated.In addition, if this design is used to produce the packing with four sides shape, then will be complicated more.
Known also and on each Sealing jaw of wrapping machine, used so-called folding rule that the path of regulating the packing thin slice makes to guarantee to make typographic pattern location correctly on the packing that processes.For for example, produce have the four sides shape packing this be known.Yet, it is disadvantageous using such folding rule, this is because if during production run, finding the packing thin slice with respect to the packing location that processes is off-square, production must stop immediately, must replace with short or long folding rule to folding rule, so that before can restarting to produce, provide necessary pattern to correct.Therefore, in other words, folding rule must be by manually exchanging, and must have many various folding rules to use, and the operator must know and use which folding rule etc. that this is disadvantageous.This not only requires great effort but also time-consuming, in addition, if production run is ended, when starting shooting once more, may introduce other problems.Usually, be to have problems in the stage of starting of wrapping machine, this is because the operation of Sealing jaw must be synchronous with material sheet.For the wrapping machine of high-speed operation,,, also can be increased to the degree that packing must be abandoned at last even in the theoretical position of a cover pattern, very little displacement is arranged if not real-time correction.For preformed perforation, sipper pore etc., by, for example, folding pull operation of living sheet and the necessary stop mechanism of braking thin slice etc. may be critical, this is because perforation may be torn or be died down, sipper pore too, this is very serious because not only the vision of packing is affected, and its function is also influenced.Therefore, the terms of settlement neither one work of being advised gets satisfactory.
Known production Tetra Classic
TM/ Tetra Classic Aseptic
TMWrapping machine be TC/TCA 65, it can obtain from the TetraPak Stalvall of Sweden.

The cam part that drawn respectively in Fig. 7 A and 7B is how this ball bearing of main shaft of Sealing jaw to be worked.It is expressed the actuating mechanism 400 that includes stepper motor 410 as shown in Figure 6 and how to work by 415 pairs of cam parts 420 of bar.Cam part 420 is fixedly attached on the fixed part of wrapping machine shell by a mechanism 418, and it can do pivotal movement around the pivot pin or the screw 419 that constitute pivot point.In Fig. 7 A, suppose that folding rule 420 is pulled back as much as possible, thereby cam part 420 is not exerted pressure on ball bearing of main shaft 26.Thereby the path of thin slice and basic setup reduced in comparison.In the situation of in Fig. 7 B, drawing, because folding rule 20 is pushed outwards moving, so thin slice (not drawing) must be taked long path.Because stepper motor 410 is via the right pressurization of bar 415 in figure, cam part 420 is just done pivoting action around pivot point along anticlockwise direction, thus promotion to add the ball bearing of main shaft 26 of spring bias voltage inside with respect to Sealing jaw 10.As with reference to figure 4A, 4B more fully as described in, ball bearing of main shaft 26 overcomes the application force of spring (not drawing) here, is pushed to folding rule 20, thereby folding rule is pushed outwards advances, in other words, it is elongated that this folding rule can be said to.
Certainly, any driver train be can use, stepper motor or multistage air cylinder device are not only, and can, for example, use hydraulic gear.Cam part also can replace with other like, as long as driver train works to the mechanism on the folding rule that is connected to movable installation in some way, so that it moves just with respect to Sealing jaw, and this mechanism ball bearing of main shaft preferably here.
At last, the part that Fig. 8 has very schematically drawn wrapping machine shell 110, in the fixed outside of wrapping machine shell the multistage air cylinder device 41 among Fig. 5.The link system that is connected with cam part 60 does not draw in this drawing, this is because it passes support or wrapping machine shell, yet the forked type rod 56 that is connected on the cam part 60 has but drawn, can also see forked type rod 58 is how to be fixedly attached on this shell, so just make cam part to make pivotal movement around the point that is connected on the forked type rod 58.In this drawing, the opposed Sealing jaw 10 that only drawn, however can see that how the ball bearing of main shaft 26 that is connected on the Sealing jaw moves along cam part 60, so just makes the position of folding rule 20 effective lengths to be controlled.As early stage pointed in this application, several Sealing jaws 10 have been installed on circulation link chain, be used for be arranged on another chain on several Sealing jaws cooperate so that clamp material sheet between them.If supply has the packing of four sides shape, two circulation link chains that add then will be arranged, on one, have opposed pressure sealing clamping plate respectively, on another, have the heat seal clamping plate.Thereby, need on the driver train that other cam part is connected to other, so that can carry out position control, also be to be used for clamping and seal operation is carried out along vertical direction previously discussed.For the sake of clarity, a part of only having drawn fixed housing, however four similar parts in fact should be arranged, wherein two are being supported driver train, and each drives a cam part.
If folding rule has prolonged, this means just in time before clamping and sealing, the material sheet long distance of must advancing, and when clamping action has started, this effect also must remain to a pair of fitted seal clamping plate subsequently, the clamping plate that for example work in vertical direction in fact clamp (and sealing) this thin slice.
Therefore,, just obtained the continuous automatically regulating of position, and the path of packing thin slice is regulated continuously by the length of control folding rule for service unit.
The embodiment that certain the present invention is not limited to specifically illustrate, but can in limit claim scope, carry out multiple change.Particularly can use any suitable drive mechanisms and testing agency.In addition, how detect can be set by different way.Only mark is set, perhaps replacedly uses the existing service unit that has been provided with for the purpose that detects or the purpose of position control.Notion of the present invention also can be used for variety classes packing, as silicon shape packing, has the packing of tetrahedron, production.
