In another embodiment, two used materials all have two-layer salable material, a side last layer.In this embodiment, produce flat lapped seam, it has and the similar character of the remainder of multilayer film, and its mechanics character make sealing when packing produce reduce by incomplete sealing and the leakage possibility that causes by forming conduit.In similar another embodiment, one of two materials all have heat sealable material on both sides, and another part only has heat sealable material on a side that engages with the other side.Because heat sealable material all is provided on the both sides of these parts is relatively costly, only on a side, have heat sealable material a material use more economically.
Seam of the present invention allows to use small-sized relatively water-tight equipment, so it can use in production environment, need not to be used to make the independent place of packing.
In packing of the present invention, at least one wall of described chamber comprises evacuator, and it is allowed by described wall is sealed the chamber that forms mutually and is evacuated.Evacuator can comprise the vacuum control check valve door that is generally used in the vacuum-packed field, and comprising can be available from the vacuum control check valve door of following industrial source: Richmond aircraft company, Norwalk, California; The Menshen packaging company, Waldwick, New Jersey; Anver Vacuum equipment maker, Hudson, Massachusetts; With Plat-o-Matic valve company, Cedar Grove, New Jersey.Described vacuum control check valve door can form in wall during making wall, perhaps after forming described wall, can seal, bonding, weld or be fused in the wall.Evacuator can also comprise vacuum outlet of the present invention.Use for some, can use many evacuators, for example to reduce evacuated time.
In embodiment of the present invention, the vacuum control check valve door can have a diameter, is pressed into connection to allow between valve and flexible pipe, for example, carries out pressure and assemble between " spill " end of " convex " of vacuum hose end and valve.Described diameter can be selected, to obtain to make rarefied at short notice flow in described chamber and pressure.For example, for the standard bale packing size chamber of 96 centimetres wide, 121 centimeter length and 127 centimetres high, the diameter of vacuum control check valve door can be 20 to 40 centimetres, preferred 25 to 38 centimetres.The size of vacuum control check valve door can be based on the diameter of the flexible pipe that is used to apply vacuum and is advantageously selected.As set forth above, can use many vacuum control check valve doors, they can have different-diameter.The number of vacuum control check valve door and size can be based on desirable speed of removing air from packing.
Though the vacuum control check valve door is favourable to being used for embodiment of the present invention, also can use other device.For example, can at least one wall of described chamber, provide standard hose fittings (fitting).Described chamber can use the standard hose fittings to find time, and then with hose fittings back or top regional seal, for example uses additional film.
Vacuum outlet of the present invention has a detailed description in Fig. 6 a, 6b, 6c and 6d, can be advantageously used in embodiment of the present invention.The embodiment of describing among Fig. 2 also comprises part 28, and it is designed to promote opening of described chamber, so that use described indoor fiber.Part 28 can be called as " easily opening " parts.The structure of easily opening parts comprises draws back band, and it is designed to be drawn back along the path that limits described chamber is torn.
To understand equally as those of ordinary skills, and can assemble and fill in many different modes in the described chamber of Fig. 1 illustrated.For example, described lower wall can be sealed to sidewall, to form opening box-shaped configuration.Fiber can be placed into the chamber of formation like this, and upper wall is placed on the described fiber.Then fiber is compressed to the height that is substantially equal to described chamber height.Described upper wall can be sealed to described sidewall then.After sealing, the inside of described chamber can use vacuum control check valve door and common vacuum generation equipment to find time, to reduce owing to the decompression of the fiber that compresses and the swelling force of the inwall that resilience acts on described chamber.
Selectively, fiber can be compressed between the upper wall of described chamber and lower wall, then with the fiber of sidewall around compression, and seals and be sealed to upper wall and lower wall mutually.After sealing, and before removing compression, described chamber can be evacuated.In an embodiment again, top and bottom sheet can be provided, in the middle of the material that they will bale packing is pressed in, top and bottom sheet is sealed each other along its edge, and before this bale packing is discharged from the compressive force that is applied, sealed package is found time.
Another kind of program is to form described chamber around the fiber volume that compresses, and removes compressive force before being found time in described chamber.The fiber of compression will expand, and be fettered by the wall of described chamber.Therefore because ambient air can not enter packages sealed, described fiber will expand generally to the differential pressure between partial vacuum or described chamber interior and the external environment, reach the swelling force balance of the fiber on the per unit skin area with described packing.Use this program, compare with the process of being found time in described chamber, still make described fiber stand compressive force simultaneously, the total body density of the fiber in the described packing is with less.
After sealing, the amount of the vacuum of taking out from described chamber will depend on packaged material.Usually, be pumped into enough vacuum, so that offset the interior swelling force of packaged material that can cause that described material expands.Usually the vacuum values of the pressure that will calculate greater than theory is used to guarantee that swelling force is balanced.Be used to pack in the embodiment of the present invention of fluffy fiber material, favourable can be that such vacuum is pumped in described chamber, and it is higher than 1/2nd barometric pressures (greater than 0.5kg/cm 2), the highest usually barometric pressure is (greater than 1kg/cm 2), be balanced to guarantee swelling force.
As described herein, in certain embodiments of the invention, the packing for example marginal portion of laminated product are sealed mutually, so that packaged material is centered on fully.Described sealing can be carried out in every way, for example described herein those.Depend on packaging size, packaged material and the amount of vacuum, it is favourable that fin seal may prove.Fin seal (fish type) can use technology known in the art and fixing device type, use constant heat or induction sealing device to produce.In production environment, advantageously promptly carry out seal operation usually, so that improve the throughput of total process.
Usually, in order to help sealing, laminate wrapping material will comprise as outermost sealing layer.Sealing layer can comprise the heat sealable poly-mer with the fusion index that makes the sealing time minimization.Usually, have been found that low density polyethylene (LDPE) provides (comprising ULLDPE or LLDPE) combination of the operating characteristic and the sealing property of usefulness.Sealing layer can advantageously have enough thickness, flows into seam and overlapping secondary seam to allow melted material.Described thickness has the minimum leaks of helping.
Fig. 3 has described to be applicable to the optionally embodiment of chamber of the present invention.As shown in Figure 3, in embodiment of the present invention, upper wall 42 can be connected to sidewall 46,48,50 (not shown)s and 52 (not shown)s in advance." opening box-shaped " configuration that obtains can comprise folding in advance sealing the margin or the pleat wing 47,49,51 (not shown)s and 53 (not shown)s.Lower wall 44 can comprise the folding in advance sealing the margin or the pleat wing 45.At least one wall comprises evacuator 56.In addition, in one or more walls, can provide and easily open part 58.The structure and material that uses in the embodiment in being shown in Fig. 3 can be described elsewhere as this paper.
The chamber of describing among Fig. 3 can be used in every way.For example, fiber can be placed on the lower wall, then remaining chamber part is placed on fiber and the lower wall, and before finding time lower wall is sealed to sidewall.
Fig. 4 A and 4B have described another possible embodiment of the present invention with the form of exploded view and assembly drawing.Packing 72 (Fig. 4 b) comprise U-bond types structure.Shown in Fig. 4 A, three walls of packing, upper wall 62, sidewall 61 and sidewall 63, part by the first U-shaped thin polymer film 60 forms, its excess-three wall of described packing, lower wall 67, sidewall 66 and sidewall 68 are formed by the part of the second U-shaped thin polymer film 65.The edge of U-shaped part can also comprise the sealing the margin or the pleat wing, and one of them is designated 64 and 69 respectively in each part.At least one wall of at least one U-shaped part comprises evacuator.
Second U-shaped part that comprises lower wall 67 can for example be placed on the bottom platen of compress.Packaged material 70, for example lamination coating can be placed on above the lower wall 67.First U-shaped part 60 that comprises upper wall 62 can be placed on then packaged material 70 above.Sidewall 61,63,65 and 68 can be folded around described material then, and use the pleat wing that the edge is sealed to another sidewall and upper wall 62 and lower wall 67, to form packing 72.Packing can be found time then.Selectively, first U-shaped part can be placed in material above, and with sidewall around described material before the folding and sealing with described material compression.
Fig. 5 for example understands another embodiment of the present invention.As shown in Figure 5, fluff material 100 can use the present invention to pack.Packing can comprise component parts 110,120,130 and 140, and they are formed by the laminated product of type described herein.
In order to help sealing, each component part can comprise the edge of bead sample, 112,114,116 and 118 on the fragment 110; On the fragment 120 122,124,126 and 128; On the fragment 130 132,134,136 and 138; With 142,144,146 and 148 on the fragment 140.In initial step, " B " can seal the edge of reply mutually to form bigger fragment.The suitable seam method that is used to form these big fragments will further specify in the description to Fig. 8-18 hereinafter.As shown in Figure 5, the edge 122 of the edge 112 of fragment 110 and fragment 120 is sealed to form sealing 152.Similarly, the edge 132 of fragment 130 and the edge 142 of fragment 140 are sealed, to form sealing 162.Certainly, if when the packing fragment can obtain with the size that is enough to form top and bottom sheet, just do not need this seam step.
Shown in Fig. 5 " C ", so the bigger fragment that forms can be placed on the top of fluff material and below, have fluff material in-to-in packing with formation.The remaining edge of packing can be sealed to seal described packing fully then.Sealing 172 and 182 is shown among " D " of Fig. 5.Extra packing will form the pleat wing 192,194,196 and 198.The described pleat wing can be folded and be sealed to the sidewall of packing, to form packing 200 of the present invention, shown in Fig. 5 " E ".
As seeing that at least one fragment of packing can comprise evacuator, to help forming vacuum in described packing from the description that this paper comprises.
Fig. 2,3,4 and 5 for example understands cuboidal basically chamber, and it will form cuboidal basically packing.The present invention includes and have difform packing.In addition, the present invention includes packing with inconsistent or random shape.As what will see from the description that this paper comprises, principle of the present invention can be used for the chamber of bag form, to produce the packing of the shape that adapts to the fiber in the internal volume of described bag.Also will obtain many characteristics of the present invention and advantage by inconsistent packing, packing although it is so for stack with stacking may not be very favourable.
Turn to Fig. 8 to 18 now, we have described and have been applicable to the edge that engages the corresponding package material segments to form several seams of bigger sheet material, for example engage fragment 120 and fragment 110 and those seams shown in the seam 152 and 162 that engages fragment 130 and fragment 140 as being respectively applied among Fig. 5.Constitute the upper and lower of bale packing shown in these big and for example above-mentioned Fig. 5 B of sheet material, 5C, 5D and the 5E.
We see that the fluff material packing can be used and with reference to the similar pack of the described method of Fig. 2 (parcel (girth wrap) on every side), wherein the multi-layer packaging material piece be wrapped up around product.Turn to Fig. 8 now, we see, in formed the straightforward procedure of packing by single piece of material, form three wing shape seams usually: along around product with two edges that form cylindrically shaped packaging form around (girth) wing shape seam 401; With wing shape seam 402 and 404 in cylindricality top and bottom.Wing shape seam 401 and top wing shape seam 402 and bottom wing shape seam 404 zone of joining produces for leakproofing material for the distribution of sealing surfaces debatable regional 403 on every side.This inconsistency that leakproofing material distributes may influence the contamination of products in package durability, vacuum-packed ability and the multi-layer flexible packing.
As seen, when they were used for forming like the cube bale packing by two sheets (each sheet itself is made of the more small fragment that engages by wing shape seam) use wing shape seam, wing shape seam especially was a problem.When the seemingly cube bale packing of the elastic fibre of packing compression, the joint of the wing shape seam of just having described is difficulty especially, and the material of the more heavy gauge that must use because of the durability demand makes problem area pack greater than the typical case.
Now part is with reference to Fig. 9 and 10, and the typical method of pre-packing external member (kit) that forms the suitable stacking of previous more detailed drafting in Fig. 5 comprises and uses wing shape seam 407 to be bonded together to form the step of bigger top-sheet 408 along an edge two multi-layer packaging materials or main leaf section 405 and 406.Similarly, with other two multi-layer packaging materials along an edge joint to form bigger bottom sheet 409.Top-sheet of describing among Figure 10 408 and bottom sheet 409 are can be on size and dimension quite similar or be identically formed.Certainly, if packing can just can be removed this initial seam step to be enough to form the size acquisition of entire top and bottom sheet.The multi-layer flexible packing of being described must use wing shape seam or sealing so that sealing medium is lumped together when forming top and bottom sheet by constituting as the heat sealable material of sealing medium and the non-tight medium on opposite side on the sheet material side that will be bonded together like this.This class wing shape seam construction is presented among Fig. 9, and two kinds of additional seams are depicted among Figure 10.
Referring to Figure 10, top-sheet 408 and bottom sheet 409 are adjusted to and are positioned at around the bale packing materials forming packing 410, form zone 412 but Figure 10 for clarity sake describes seam with the top-sheet 408 that contacts with each other and bottom sheet 409 on sizable area.In fact, the lower platen that bottom sheet 409 next-door neighbour is used to compress the packing apparatus of fiber is placed, then fiber is placed on this bottom sheet in the pinch device, after this on fiber, place top-sheet, with pinch device fiber is compressed, and for example use wing shape seam on all four sides of this bundle, top and bottom sheet to be sealed.Thus, as shown in Fig. 5 C, sheet material next-door neighbour wants under the situation of lamination coating of bale packing and is in engaging of realization top-sheet and bottom sheet under the situation of impaction state at fiber usually.Thus with the top with bottom sheet lumps together and the edge wing shape on all four sides engages along them, thereby form sealing bale packing 410 as shown in Figure 10, perhaps as among Fig. 5 E as shown in the bale packing 200 like that.The illustration of Figure 10 provides the problem area that forms in two wing shape seams (forming top-sheet 408 and bottom sheet 409 by it) when this bundle lumps together, or conduit 411, will be further described below the problem of this conduit 411.
Referring now to Figure 10 and Figure 11,---it is the section drawing along the dotted line jointing line 412 of Figure 10, has shown the top and the bottom sheet that are bonded together, those of skill in the art will recognize that when using these seam constructions to run into some problems.Problem is that these wings (fins) become physical obstacle when using various sealing arrangement, even also be like this at seam portion 412 places away from conduit 411.Another problem is the folding of material in the wing shape seam because 180 degree are crooked and for realizing that seam 412 applied pressures die down seam at 436 places.Another problem is that folding material is in the action of the spring at 413 places or rigidity and hinder the avalanche of conduit 411.A problem is the thickness of several layers again, for example at 414 places, causes being difficult to by the multilayer heat seal.As seeing like that clear among Figure 11, the sealing area injustice, so be difficult to apply uniform pressure.Another problem is that the size of conduit 411 and the orientation of the folding sealing layer that causes cause that usually leakproofing material is not enough to fill up fully the situation of this conduit, and is relative thinner because sealing material layer is compared with the size of conduit 411.When packing can obtain with the size that is enough to form entire top and bottom sheet, then this seam step was unnecessary.But, when the undersize of packing when forming entire top sheet material or bottom sheet, and, developed seam of the present invention so that will be bonded together than the packing of small fragment to obtain sheet material even as big as the upper and lower that constitutes the lamination coating bale packing in view of some shortcomings of the wing shape seam of just having described.These seam portion of the present invention have solved each the problems referred to above.
On the one hand, turn to Figure 12,13 and 14 now, the disclosure provides the use of two lapped seam, it comprises two fragments 415 and 416, be referred to herein as the main leaf section, add (narrower usually) the 3rd sheet material 417, it all has heat sealable poly-mer on two surfaces, for example LLDPE or ULLDPE are known as sealing band 417 at this.This pair of lapped seam is two lapped seam that are close to each other substantially, and lapped seam 418 snaps into main leaf section 415 and 416 on the sealing band 417 separately.Seam comprises that thus the edge 419 of a main leaf section 415 is parallel with the edge 419 of another main leaf section 416, join with another main leaf section edge 416 or link to each other, or between has minim gap.Each main leaf section snaps on the sealing band 411 along seam 418 thus.This fillet 411 by the double-side material that engages with main leaf section 415 and 416 engages main leaf section 415 and 416 side by side.Use bigger top that two lapped seam form and bottom sheet only to be connected on the sealing band but not be connected to each other, therefore needn't overlap main sheet.Although preferred embodiment does not overlap each other main sheet, for aesthetic reasons, for example in order to make patterns of material coupling, main sheet can have small overlapping.
Use this pair of lapped seam to form the above and below sheet material and have many benefits.A benefit is to have the risk that the lower formation of finding causes the conduit of leakage when using wing shape seam when after this above and below sheet material that engages being connected to form the upper and lower of bale packing.Referring now to Figure 13 and 14,, although may form sulculus road 421 at the end of dowel bar 417, this seam causes this cavity blocked 420 in the mechanics character in when sealing, mainly be because the conduit 420 that is arranged in the dowel bar edge less than 1/4 of the above-mentioned conduit size of finding in wing shape seam.In addition, the height at 421 places is that layer of material is thick, but not the two layers of material in wing shape seam adds the folding extra height that increases.In addition, in certain embodiments, can use the sealing band thinner,, thereby the size of this conduit further be narrowed down because sealing partly is subjected to covering the protection of the fragment of sealing bar with bar than the fragment that is used to form sheet material.In addition, the width of conduit 420 is half that find in wing shape seam in two lapped seam, because this pair lapped seam is divided into two independent conduits 420 with this width.In addition, because the main leaf section of material is not folding at this seam, almost or fully there is not action of the spring to hinder the avalanche of little conduit.Two lapped seam are also more attractive in appearance than wing shape seam, because it spreads out flatly, and the surface on the whole seam has smooth appearance, because two main sheet are placed side by side, covered from the 3rd sheet material to small part visually.
Turn to Figure 15 now, described another embodiment, wherein single lapped seam combines with the use of multilayer film, and at least one multilayer film all has salable material, for example LLDPE or ULLDPE on the two sides.In this embodiment, the single lapped seam shown in two main leaf sections 422 and 423 with dashed lines 424 is bonded together to form bigger sheet material.In this embodiment, below sheet material 423 is two-sided, and top sheet material 422 can just have heat sealable material only in the bottom on the one side adjacent with bottom sheet.Subsequently can be with the big sheet material that this method produces according to packing in the external member with aforementioned similar mode or as shown in Fig. 5 E and Figure 10, being used in before.If the two sides of two sheet materials all has heat sealable material, then strictly speaking, there is not the branch of end face and bottom surface in these sheet materials because arbitrary face can be in final bale packing inwardly or outwardly.But, if top-sheet only has heat sealable material on the bottom, then must keep the orientation of sheet material, therefore also this sheet material wing shape is joined on the edge of the bottom sheet that constitutes this bale packing bottom by the edge of digging top-sheet, can finish this bale packing.
In packing of the present disclosure, can use the seam of just having described of the present invention so that two are bonded together to form big sheet material than small fragment, avoid using wing shape seam and aforesaid subsidiary problem thereof simultaneously.Seam as herein described can use the method for heating of any kind to finish, for example constant resistance, pulse resistance, ultrasonic or induction.Preferred embodiment is pulse and constant resistance heat.Seam can be used to produce sealed package as herein described or packing external member with the various flexible multi-layer materials that have heat sealable material on one or both sides.
Of the present disclosure pair of lapped seam can be used standard seal equipment, and for example rotating band sealer or folder type impulse sealer are made continuously, and do not need to use large-scale special machinery.
In a kind of method that produces the seam of just having described shown in Figure 16 target that forms of two lapped seam (wherein with), two multi-layer flexible packing main leaf sections 425,426 that will have salable material according to size Selection and on one side superpose each other, and wherein non-tight faces towards each other and salable layer faces outwards.Sealing band 427---made and enough wide to be convenient to use and the same long with the seam of making by the packing that heat sealable material is all arranged---length along upper segment is placed (and can pat (tap)), and wherein the only about half of width of sealing band is superimposed upon on the main leaf section of top on the two sides.Then whole assembly set is turned over, and additional dual face seals material is folded into (and can pat the location) on the second main leaf section, so that its image pattern 16 is such.
Drive belt sealer or other heat-sealing equipment move so that it is sealed to the dual face seals material on two fragments at 428 places along the length of assembly set subsequently.Main flexible packing material sheet is owing to sheet has the fact on non-tight surface toward each other and sealing each other.
This assembly set can launch subsequently and described continuation prepares the packing external member with reference to Fig. 5 as mentioned.
Although the method for just having described is the method for optimizing that produces seam in developing vacuum packaging, other method is also available and be that those skilled in the art understand easily.We point out, the method for just having described also can be with the equipment continuous handling of industrial strength to produce wide sheet material to the fluff material that is enough to be used in packing acetate tow and so on.
Turn to Figure 17 and 18 now, in other method, can use the standard edge water-tight equipment to produce single lapped seam of the present invention.With reference to Figure 17, will on the two sides, all there be the first main leaf section 429 of salable material to put in one plane and the edge turned up so that this sheet material can self sealss, for example by not sealable sheet material 430 is provided at interlayer.If this sheet material is made of the dual face seals material, then this not sealable sheet material 430 must be to avoid this sheet material self sealss between flap and all the other main sheet.But, if main sheet has only one side to have heat sealable material, then do not need shim, can will there be the face of heat sealable material to go back on the main sheet as shown in Figure 18.If two main leaf sections have only one heat sealable material is all arranged on the two sides, then refer again to Figure 18, on the two sides, all there is the sheet material of heat sealable material folding with not being.
Refer again to Figure 17 and 18, no matter main leaf section 429 or 431 is to have heat sealable material on one side or two sides, on first sheet material 429 or 431, be superimposed upon subsequently the second main leaf section 432 that has heat sealable material on the two sides or 433 so that second or the edge of top main leaf section 432 or 433 be located immediately on the folded edge of bottom sheet.Water-tight equipment is moved to form seam 434 or 435 along this edge.
According to above understanding easily, seam of the present disclosure can be used for multiple fluff material, comprises staple commodities, for example the multiple vacuum packaging and the vacuum-packed technique of cellulose acetate tow and other material disclosed herein as those skilled in the art.These class staple commodities include but not limited to, Agricultural Materials, lamination coating, textile material or the like.Therefore the disclosure provides bale packing, packing, packaging system, packing method and packaging facilities as described herein.
