Description
Technical field
Place of the present invention be to produce at the ends in the all-key footwear, the end and the field that increases the footwear inner stuffing of foot's comfort level in the little footwear.More precisely, the present invention includes a kind of method, this method is used for the end in a large amount of production all-key footwear, the end in the little footwear, and the footwear inner stuffing that increases foot's comfort level, comprise with the template of ideal form and compress the footwear inner stuffing that cuts the different-thickness that obtains.Elastomeric material is placed on the above-mentioned template, material is pressed in the chamber of above-mentioned template, in the step of compression, along the surface of template this elastomeric material is cut with cutting tool.Furtherly, this invention also comprises final products, and the interior end of footwear of desired shapes and thickness or the filler that elastomeric material is done are promptly arranged.
Background technology
Some methods about the end and filler in the production footwear are formerly arranged in the technology.Method the earliest is for example by the method with the die-cutting machine cutting that discloses among the EP011006.This method can be cut all material and is applicable to a large amount of productions at the end in the footwear.The outer shape of final products depends on the shape of employed die-cutting machine.The disadvantage of this method is that the thickness of final products is identical with the thickness of the material that is cut, and also, the end in cortex of cutting with die-cutting machine or the foam shoes, its integral thickness will be identical with the use thickness of same leather and foam.Therefore, this method is not suitable for the different functional footwear inner stuffing of production thickness.For example, only covered the little footwear inner stuffing of the part of inner sole, if only covered heel or sole part, so, will make troubles to the user with the words that the method for die-cutting machine is produced, because the edge of footwear inner stuffing can not be level and smooth fit with inner sole, and external margin and shoe-pad are fitted, can make the edge become very uncomfortable again.Therefore, be difficult to produce the little footwear inner stuffing that does not cover whole shoes surface, and the edge that makes this kind filler is than intermediate thin with this kind method, thus can guarantee with footwear in the perfect applying in the end, the user is felt comfortably cool.Simultaneously, also be difficult to produce with this kind method and be applicable to different foots, the end in the different functional all-key footwear of thickness,, this is readily appreciated that, because need to use elastomeric material that thickness model is provided.
There is a specific three-dimensional model of usefulness to produce the common method of the interior end of footwear or footwear inner stuffing, also, at US7,157,028B2, US2005/0060910A1 or US 3,684, the method for passing through injection moulding generation different-thickness that discloses among the 420B.Compare with the method for above-mentioned use die-cutting machine, this method can be used for producing the interior end of footwear or the footwear inner stuffing of different-thickness, and three-dimensional thickness model.The main disadvantage of this method is that the process of this method is quite complicated, comprises the polymer injection model, waits for that the polymer thing solidifies, and removes mould then and does not damage product.What is more important, with the interior end of footwear that this injection molding method is produced, accuracy is lower, and after removing mould, the edge also has slight wearing and tearing sometimes.In order to produce the end and filler in the high-quality shoes, these faulty edges also will pass through secondary cutting, and this has just spun out production process.The another one disadvantage of this method is that the polymer that uses in this method must be to can be used for injection molding polymer.But in general, such polymer does not have the due ideal characterisitics in the end in the footwear, such as for the comfort level of shoes very important good moisture absorption and damping property highly.What is more important, these polymer all have tack usually, and in other words in case there is dirt to assemble, they just become and break away from or loose.Therefore, in order to be attached on the surface smooth as leather or dermatine (polyurethane), these materials must be clean.In case assembled dirt on the surface of these materials, they must be cleaned, so that fit with inner sole again.In addition, this material can not be used to shaggy footwear, as the footwear of suede or the shoes of embossment leather are arranged.However, with die-cutting machine cutting opposite be, this method is very suitable for producing the end in the three-dimensional footwear, production process comprises many steps.Therefore, this method be not suitable for simply, the end in a large amount of production footwear of high benefit.
US 5,688, and 538 have disclosed a kind of method of producing three-dimensional shape on elastic foam.Synthetic foam is by a figuratum pressure roller extruding, and a level and smooth pressure roller props up a side cut, and this sides cut is adjacent and tangent with this figuratum pressure roller, but with the level and smooth certain space of pressure roller maintenance, thereby on foam sheet, remake out the pattern of a solid.This method is applicable to the surface of a large amount of production moulding on elastomeric material.But this method does not comprise the step that cuts out X-Y scheme from foam sheet, so itself is not suitable for the end in the production footwear.
The method of the end or filler is by US 4,351 in the footwear of another kind of simpler production different-thickness and shape, the method for the 211 compression cuttings that disclose.Desirable elastic foam is placed on the cavity template with ideal form.Elastic foam is pressed in the cavity of template, and cuts in the process of compression.The product that finally obtains is the reprint of template cavity.In order to produce the different footwear inner stuffing of edge thickness, the cavity of template need comprise the diapire that different depth is arranged.
US 6,176, and 164 have disclosed a kind of foam compression cutting method of improved.According to US 6,176,164 invention need be supported a template that comprises the cavity of finalizing the design with a mobile workbench.Foam is placed on the template, and the workbench that moves moves at a right angle under the conveyer belt and moves, and foam moves under the conveyer belt at this right angle and is pressed in the template cavity.A mobile blade cuts the foam block that is compressed on the surface of template.The improvements of this method are, in whole process, will cut second same foam block, and this second foam block is placed on first above foam block, in the process that is moved the conveyer belt compression, have increased the pressure of first foam block.The foam of being produced is the reprint of accurate more template cavity.But US 6,176, and 164 do not point out how to make the upgrading of this kind method, to be used for footwear inner stuffing a large amount of production pinpoint accuracy, that shape is identical.For producing in this way at the end in the footwear, the very important point is, employed elastomeric material will be compressed uniformly, and also, all sites will be pressed into identical pressure in the template cavity.The more important thing is that cutter will just be cut at the template housing surface.If for the compression of elastomeric material or cut inhomogeneously, the shape of final products is with undesirable.For coming the end in the identical footwear of a large amount of production with comprising more than the template of a cavity, crucial more is that template must be adjusted on the same level, to guarantee that cavitys all in the template suffered extruding in the compression cutting process is identical.For US 6,176, the little template of having only a cavity that discloses in 164, this adjustment for template is not crucial.But for problem how to guarantee that all cavitys in the multi-cavity phantom plate all are subjected to same pressure and are evenly cut, US 6,176, do not provide answer in 164.
Summary of the invention
Above-mentioned technology formerly, or be not suitable for the footwear inner stuffing of producing different-thickness, or step is too many, also or be not suitable for and be upgraded to a large amount of productions.One of purpose of the present invention just provides simple, a quick and economic method, and this method is applicable to comfortable, the high-quality of a large amount of productions, and has the footwear inner stuffing of ideal form and different-thickness.Special needs to be pointed out is that the high quality of products on the meaning of the present invention refers to produces the end or filler in a large amount of identical footwear, and guarantee that the interior end of all footwear or the filler of same sign all have high-quality.
The present invention further target is that footwear for all kinds provide functional filler, for example, the picture pad is at the little footwear inner stuffing of the front portion of pin, and it both can be used for not peep toe, also can be used for slippers, and can be used to have the high-heeled sandals of slippers pattern shoestring especially, or the footwear inner stuffing of all-key, some raises up, according to the kind of purposes, shoes and pin, support metatarsal, supinator, pronator, arch of foot, or other wants the position of the pin that supports.
By simple and economic, as can to produce the footwear inner stuffing with a desired shapes and different-thickness in a large number method is provided, this invention has solved the problems referred to above.
This invention is one and passes through the compression cutting, a large amount of methods of producing the footwear inner stuffing with different-thickness.Described method comprises the steps: 1) with one movably workbench support a template, this template comprises the template cavity of more than one moulding; 2) with permanent plant this template is fixed on the workbench movably 3) elastomeric material that will cut is placed on the template 4) workbench of template is arranged and be placed on fixing right angle by mobile device and move elastomeric material below the conveyer belt, above-mentioned elastomeric material is pressed in the template cavity of moulding 5) with band blade elastomeric material is cut; The characteristics of said method furtherly, also comprise the step of adjusting the horizontal guideline of the template on the workbench movably with adjusting device.
Use the advantage of this adjusting device to be, have the large form of a plurality of cavitys can be used to be implemented in the step, produce a large amount of footwear inner stuffings simultaneously.The committed step of producing high-quality footwear inner stuffing with this method in a large number is, the accurate adjustment that the template on the workbench is carried out.Only carry out accurate horizontal adjusting in the micrometer range for the template on the removable workbench, just guaranteeing to be moved conveyer belt, to be pressed into the suffered pressure of the elastomeric material in all template cavitys on the template identical, aspect by the cutting of band cutter is also identical, thus the identical product of output.No matter be for mobile conveyer belt, the band cutter, still travelling table carries out so accurate adjustment and all is not easy because all parts all be usually fix, several the composition firmware of big machinery weighs.Attempt to adjust so heavy parts with it, simpler method is to adjust the horizontal guideline of the template on the removable workbench.
For adjusting the horizontal guideline of template, a desirable implementation method is after being fixed on template on the workbench for the first time, before the elastomeric material that cuts is placed on the template, use adjusting device, carry out the step that the horizontal guideline of the template on the removable workbench is adjusted.In for the first time fixing step, fixture is not completely fixed, and is convenient to adjusting device the horizontal guideline of masterplate is adjusted to reserve specific space.Then, when needs, adjusting device is inserted in the supporting prefabricated template cavity.The directrix of template will be adjusted the removable workbench below adjusting device is run into by promoting adjusting device by the cavity in the template.By further promotion adjusting device, template will be adjusted device and mention from the workbench that moves.After all adjusting devices all were pushed into, template had been lifted to desirable height, was horizontal with mobile conveyer belt and band cutter, and the template device that will be fixed is fixed on its final position then.
In a preferable implementation method, adjust the step of the horizontal guideline of the template on the removable workbench with adjusting device and only carry out once, and be before carrying out following continuous cyclic process: 3) elastomeric material that will cut is placed on the template; 4) move elastomeric material below the conveyer belt by moving the workbench fixed template and being placed on fixing right angle, above-mentioned elastomeric material be pressed in the template cavity of moulding 5) with band blade elastomeric material is cut; In these circulations, do not need template is further adjusted.
This method can be produced the footwear inner stuffing in a large number by repeatedly circulating, and need not interrupt whole process in order further to adjust.In this implementation method, as long as employed template is constant in producing with this kind method, template does not just need to be adjusted.
In the implementation method of another template of the present invention, be applicable to that the full-size of template of the present invention reaches 1.20m x 1.20m.Minimum range between each template cavity is 2mm, and a desirable distance is that 4mm is to 6mm.This template can be held a large amount of template cavitys, and concrete quantity depends on the 2D shape of each cavity.The remarkable advantages of this multi-cavity phantom plate is that it makes the method among the present invention can be used for carrying out the production of footwear inner stuffing in enormous quantities.
The template of using in this method can be with the wooden mixture manufacturing of any kind, for example the melamine that had occurred in technology formerly.In a desirable implementation method, template is an aluminum, because aluminium can better be kept out environmental factor, as the influence of humidity.To the test shows of different templates, the aluminum template is applicable to the manufacturing of the interior end of high-precision footwear or filler more.
In a comparatively feasible implementation method of the present invention, this method is to implement from organize the elastomeric material of selecting material with next with a kind of: latex foam, polyurethane foam, the ethylene vinyl acetate foam, polyvinyl chloride foam, polyethylene and fine-celled foam, polyurethane more preferably, preferable is highdensity flexible polyurethane elastomer.
A kind of desirable elastomeric material is selected from polyurethane foam among the present invention, because they have the damping property of height, and maximum comfortable conservation degree and better elastic, and its pervious bed can make steam and sweat away from foot.
In an implementation method of the present invention, the template cavity of typing only has a diapire on a degree of depth level.
In another implementation method, above-mentioned elastomeric material is an elastomer, and its hardness is between Shao Shi O12-70.Although the template cavity has only a degree of depth level, the footwear inner stuffing that draws with this kind method contains not only thickness.
One further in the implementation method of the present invention, have at least the edge of a template cavity can comprise the cavity of a protruding pentagon (five-pointed star), circle of five summit coileds, the summit of highest point is than other four centers that five-pointed star is approached on the summit more.According to the present invention, use the advantage of this template cavity to be in the method, the footwear inner stuffing that draws can be used to the shoes of common specification, and also i.e. peep toe not has the peep toe of common sandals band and the peep toe of folder flip-flop band is arranged.At peep toe not with have in the peep toe of common sandals band and use these footwear inner stuffing to put together with the front portion (three summits) of five-pointed star, point to toe-cap, comfortable pad is at the sole position.In this implementation method, there are two summits at the rear portion of this five-pointed star towards the rear portion of footwear (details is referring to accompanying drawing 4A).Same footwear inner stuffing also can be used to the peep toe of folder flip-flop shoestring, in this footwear inner stuffing inversion and footwear, also be, towards the front portion of footwear, the folder toe shoestring that the recess between such two summits just can hold between large toe and second toe is fixed on herein (details is referring to accompanying drawing 4B) with the rear portion (two summits) of five-pointed star.A remarkable advantages of this dual usage is that a kind of footwear inner stuffing can use and all different types of shoes, need not further to carry out the cutting in cavity or space, just can be applicable to folder toe shoestring.
In another implementation method of the present invention, the template cavity in this method has 2 to the thick sidewall of 70mm, more preferably 4 arrives 10mm.According to the present invention, if use the elastomeric material of respective thickness according to the degree of depth of template used cavity, the footwear inner stuffing that draws with this template cavity that the sidewall of 4 to 10mm thickness arranged so, position, intermediate portion (positions of pad footwear) will be the thickest.De Taigao can not lifted in foot and be cut in the belt to such an extent as to this thickness can better be guaranteed this footwear inner stuffing, or because a part has been lifted by foot, and make pin be in uncomfortable position at shoe lining.
In another one implementation method of the present invention, the thickness of employed elastomeric material is 2-10mm, consequently the middle part of footwear (positions of pad footwear) thickness is 2-10mm, to such an extent as to foot can not lifted De Taigao and be cut in the belt to guarantee the footwear inner stuffing, or because a part has been lifted by foot, and make pin in shoes, be in a kind of uncomfortable position.In this kind implementation method of the present invention, employed template cavity has sidewall, and the thickness of sidewall is more than or equal to the thickness of employed elasticity material.Therefore, elastomeric material will only can be extruded at the surface and the edge of template cavity, and mid portion will be deep in the cavity (details is referring to accompanying drawing 3A) fully.
Furtherly, the present invention is relevant with the footwear inner stuffing that is produced by above-mentioned arbitrary implementation method.In an implementation method, the footwear inner stuffing comprises an edge less than 90 ° inclination, and more desirable angle is less than 45 °, and more desirable angle is less than 30 °.A quite slight inclination at the edge that tilts, perhaps better also promptly less than 45 ° less than 30 °, for the comfort level of footwear inner stuffing, be advantageous.According to the little footwear inner stuffing that this kind implementation method of the present invention is produced, just can not cover the whole width at the end in the footwear from design.Therefore, the edge of footwear inner stuffing can not touch all sides of shoes leather, can not form a uniform second layer, but still tightly fit in the interior end of meeting and footwear.If the edge that tilts is very steep, reach maximum 90 °, this edge will be very uncomfortable, and on the contrary, less than 45 °, can well fit with the end in the footwear in the edge of perhaps better slight inclination less than 30 °, thereby make foot more comfortable.This footwear inner stuffing is enough wide, can cover the width of pin, but again not as good as the width of end the widest part in the footwear, also, the position of forefoot it is advantageous that, can be used to various different types of shoes.According to design, this footwear inner stuffing can be used for narrow high-heeled sandals easily, can't influence attractive in appearance because of the edge that exposes filler.
In another implementation method, be that 5cm is to 9cm according to the Breadth Maximum of the footwear inner stuffing of above-mentioned either party's manufactured.In the implementation method of a little footwear inner stuffing, more desirable Breadth Maximum is 7cm.This width is desirable, because the width of the sole of the narrowest shoes part is about 9cm.Therefore, the little footwear inner stuffing about the wideest 7cm goes for all such shoes.

The specific embodiment
The present invention is with a kind of relevant by compressing the method for cutting the little footwear inner stuffing of producing different-thickness.Use contains the template of ideal form, and desirable elastomeric material is placed on the above-mentioned template, above-mentioned material is pressed in the template, and according to the external margin of shape of template, in the process of compression, cutting elastic material.Further, the present invention is with relevant with the footwear inner stuffing elastomeric material manufacturing, that desired shapes and thickness are arranged.Accompanying drawing 1 has been showed of the present invention improving one's methods, and it comprises a removable workbench 1, and a template 2 and surface 3 thereof are arranged above, and template cavity 4 device 5 that is fixed is fixed on the removable workbench 1.Make the required elastomeric material 6 of footwear inner stuffing and be placed on the template 2, covered whole template cavity 4.1 towards mobile conveyer belt 7 of removable workbench moves, and mobile conveyer belt 7 is fixed on travelling table 1 top with less than 90 ° angle 8.In case touch zone below the moving conveyor belt with the template of elastomeric material 6, elastomeric material will be pressed into the template cavity by pressure, this pressure is selected by the fixed angle 8 of adjusting mobile conveyer belt 7.Under best pressure, elastomeric material 6 cuts device to be cut, blade that for example is moved or the cutting of band cutter, and cutter sweep is along the surface cutting of template.In order clearly to show, a simple blade 9 has been described among this figure.By the final products 10 that cutting elastic material 6 gets, be the reprint of template cavity 4.
Accompanying drawing 2 has been showed the more in-plant view of a desirable implementation method of the template 2 among the present invention.The template cavity of this template comprises that a sidewall 13 is identical with the thickness 16 of a diapire 14. sidewalls 13 in whole cavity.Diapire 14 has only a degree of depth in the template cavity.Elastomeric material 6 occurs with the form of sheet material, has only a thickness 12, and the product that uses this template to produce has different thickness.Special needs to be pointed out is that it comprises the edge 12 of inclination, tilt with specific angle 13.
Accompanying drawing 3A has showed and elastomeric material is being pressed in the stage of template method used in the present invention.For the purpose of clear and definite, in this figure, will be described as the compression of elastomeric material and be pressed into simultaneously in the whole template cavity.In fact, workbench moves below conveyer belt, so have only elastomeric material below the conveyer belt to be compressed as described in just can looking like.Be placed on the elastomeric material that under conveyer belt, moves then on the template, can be compressed by said conveyer belt.At the lip-deep elastomeric material of template 3, material thickness can be compacted into thickness 12.That part of elastomeric material that is pressed into the template cavity fully can be expanded in the cavity.According to the thickness 12 of elastomeric material, the degree of depth of template cavity, and the fixed angle of mobile conveyer belt, this elastomeric material can expand to its initial state, thickness 12 (as shown in the figure), or thinner than initial state.Compressive state can be divided into 3 zone: A, B and C.In the A district, elastomeric material can fully be expanded, and in the B district, at the edge of template cavity, elastomeric material is by powerful more compression.C has described in the district state that elastomeric material is compressed fully at template surface.At compression stage, use the resulting product of cutter sweep cutting elastic material that moves along the surface of template 3, edge (B) is thinner than mid portion (A).The top of elastomeric material will be the top of product 18, and the bottom of elastomeric material in cavity will be the bottom of product 17.
Accompanying drawing 3B, after cutting, material returns to common state, and product has the edge of inclination.The angle 19 of the inclination of sloping edge depends on elastic modelling quantity, the thickness of elastomeric material 12, and the fixed angle of conveyer belt, the pressure when also promptly compressing.
Accompanying drawing 4 has been showed desirable product implementation method among the present invention.According to this implementation method of the present invention, the footwear inner stuffing comprises a front portion 21 and a rear portion 22.When being used for common shoes, also i.e. peep toe not perhaps has the peep toe of common shoestring, have that the front portion 21 of three " ears " can be comfortable, fill up at the sole place completely, it will be placed on the front portion (accompanying drawing 4A) of footwear.Identical footwear inner stuffing also can be used to reveal the pinch slippers of toe, to have only the rear portion 22 of two " ears " to be placed on the front, the space between two " ear " just can be good at holding the pinch belt (accompanying drawing 4B) between large toe down and second toe so.Accompanying drawing 4C has showed the rear portion of footwear inner stuffing 24, and belt that can an attached viscosity is fitted to guarantee in footwear inner stuffing and the footwear end.
From accompanying drawing 3A as can be known, the elastic modelling quantity of used elastomeric material is depended at the angle of inclination of product.Therefore, in this kind implementation method of the present invention, suitable material will be selected from the elastomeric material between the hardness Shao Shi O12-70.Desirable elastomeric material is the highdensity flexible polyurethane elastomer of shore hardness O between 12-30.
Preferable above-mentioned elastomeric material is selected from polyurethane, because they have the damping property of height, and maximum comfortable conservation degree and elasticity, and poromeric material can make steam and sweat away from foot.
A property of this implementation method of the present invention is that the template of using in this method contains a template cavity, and this cavity only has diapire on a degree of depth level.But the product that draws by compression cutting does not but have only a thickness, and also, the angle of inclination is less than 90 °, less than 45 ° better, preferable is less than 30 °, to guarantee comfortable the fitting at the end in the footwear of footwear inner stuffing.Therefore, product is not the reprint of template.A main advantage of this kind of the present invention implementation method is to produce the template that thickness is identical on the diapire to have the template of sloping edge easy than producing, and cheap.
Another advantage of this kind of the present invention implementation method is the difference according to the degree of compression, and the physical property difference of selected material, and the gradient that is drawn also is different.The degree of compression can change by mobile conveyer belt on the adjustment template and the distance between the template.Distance is big more, and pressure is more little, and vice versa.Therefore, from the above, same template can be used to produce different inclined-planes, and thickness depends on pressure, the physical property of employed elastomeric material, and the degree of depth of template cavity.Pressure is low more, and thickness is more little, and vice versa.
Accompanying drawing 5A has showed a big template 26, and it has a plurality of template cavitys.In this figure, according to an implementation method of the present invention, the shape of template cavity 27 is suitable for producing the little footwear inner stuffing that supports heel.This template is fixed on the removable workbench by several fixtures 5.Adjusting device 28 is positioned in the template with about spacing of 10 to 30cm.Distance 29 between the template cavity is 2mm at least, more at least between 4-6mm.Spacing will produce substandard products less than the template cavity of 2mm.In an implementation method of the present invention, adjusting device 28 is placed on each limit of fixture 5 along the external margin of template, the pulling force that is subjected to balanced template.Since the distance between the template cavity is all done usually try one's best little, to produce maximum products in a circulation, fixture 5 and 28 of adjusting devices on template residue position are separated to place.
Accompanying drawing 5B has described a desirable implementation method about fixing and adjusting device according to the present invention.Left figure has described the nut of set bolt 30. set bolts 31 of a standard can be bigger than axle.The length 32 of set bolt is greater than the thickness of template, can be driven in the removable workbench with the bottom of guaranteeing bolt, thereby template is fixed on the removable workbench.The described adjustment bolt 33 in the right, its nut 34 is the same wide with axle, and therefore whole bolt can be driven in the cavity of the moulding in advance that matches in the template.Opposite with the length of bolt 32, adjust the length of bolt 35 and the thickness of template and have nothing to do.
How accompanying drawing 5C has showed with set bolt 30 and has adjusted bolt 33 a big template 26 has been fixed on the removable workbench 1, and adjusted.For the purpose of clear and definite, the gradient of removable workbench is extended.For the horizontal positioned template, guarantee even compression and cutting for elastomeric material, be fixed bolt 30 of template is fixing.The nut of set bolt is squeezed into template fully, and the surface of template can keep smooth like this.If set bolt exposes from template surface, the band cutter will be damaged when cutting.Adjusting bolt 33 will be driven in the suitable cavity of moulding in advance, up to running into travelling table.Opposite with the set bolt 30 that is driven into workbench is to adjust bolt 33 and do not enter workbench.Afterwards, adjusting bolt 33 will be by the darker template of squeezing into, and by the reaction force of pushing workbench 1 template is held up.Template can be held up certain height, to guarantee with mobile conveyer belt and to be with cutter ideally on a horizontal line.Hence one can see that, and the cavity of the moulding in advance in the template all is not used to.Some part need be raised to keep perfect level consistent with the directrix of template, has only the cavity in these parts just can be used, and is driven into the adjustment bolt.
