The specific embodiment
The first embodiment of the present invention is shown among Fig. 1-Fig. 4.Insert 10 is characterised in that to have buffer unit, and this buffer unit is circulating air between bottom 12 and upper strata 14.Air is directed into the appointed area of insert 10 via hole 16, and hole 16 circulating airs are to user's pin and cross user's pin.Bottom 12 and upper strata 14 are separated by air layer 18, or alternatively, but the intermediate layer can be foam or other breathable in light weight (breathable) materials.Though also can comprise in the present invention such as other buffering embodiment such as gloves, knee-pad, this insert shape is made the inside that conforms to the profile of people's pin and be engaged in footwear closely.The basal surface 20 of insert 10 comprises multiple deformable geometry, for example the object 22 of evenly spaced reverse domed shape roughly on whole basal surface as shown in Figure 3.The domed shape structure 22 that can be used as the viscosity point that connects adjacent layer is configured to when for example subsiding under the pressure the user owing to taking a step to apply weight, thereby forces air to be escaped and at the shoe lining face and around the bottom circulation from the structure of domed shape.Some air are forced through the hole 16 of vertically extending between bottom 12 and top layer 14, the air below the discharge sole.Therefore the structure 22 of domed shape not only cushions pin with its weight capacity by some energy that absorb from the downward pressure of pin, and provides around this insert and the vertical forced air flow by insert in appointed positions.
Insert preferably is formed with projection or the wing 26 that extends laterally, and it extends upward in order to conform to the profile of user's arch of foot from basal surface 12.The upper surface of wing is level and smooth, and its lower surface 26b is characterised in that substantially the groove 28 of the cylindrical shape of extending along the height of wing 26.The arc 32 that can extend to vertically slightly higher than the height of heel 34 is formed on the top of wing 26.The groove 28 of cylindrical shape provides two purposes, and namely they are that insert 10 increases rigidity, and the outside along insert provides vertical passage simultaneously, is used for air and moves to top surface from basal surface.These passages or groove when the structure 22 of user walking and compression domed shape, help the to circulate air of footwear inboard.The periphery of insert 10 can comprise the lip limit 30 of extending around insert.Lip limit 30 can help insert 10 is positioned at the footwear inboard and prevents that insert from moving, and can form semitight with the inner surface of footwear, passes through the vertical hole 16 of extending to force more air between lower surface 12 and upper surface 14.
Fig. 4 a and Fig. 4 b illustrate the cross section of insert 10, and top surface and basal surface that the intermediate layer 18 that is preferably air separates are shown.In optional embodiment, air layer 18 is replaced by the gas permeable material of soft permeable foam or other lightweights.The structure 22 of domed shape is roughly extended length and the width of basal surface, and extends in the foamed material 18 only about half of between lower surface 12 and upper surface 14.The structure of each domed shape has and adjacent profile at interval curved profile equably.Similarly, vertically hole 16 also is evenly spaced apart (but alternatively can be brokenly at interval for the purpose of various functions and decoration), and 14 extend from basal surface 12 to top surface, thereby the passage that provides air to pass to the top of insert from the bottom of insert.When weight put on insert (will take place) when the user takes a step, the structure 22 of domed shape was subsided under the weight of user's pin, forced the air in the cavity that is collected in domed shape structure 22 to be discharged from along the basal surface of insert.The shape of dome, thickness and material behavior are selected to predetermined speed subsides so that the air of controlling by shoe-pad flows.The assistance of the air of some this discharges by the groove 28 of vertical cylindrical shape will be flowed around insert, and groove 28 guiding air from the side of insert upwards and cross pin.Air also will be forced through vertical hole 16, and preferred hole 16 concentrates on below the heel (ball) of pin and the arch of foot and in the loe zone.The air that passes insert via vertical hole makes the pin cooling and insert is ventilated, and helps to prevent that moisture from concentrating in the footwear.When the user lifted his or her pin, the structure 22 of flexible domed shape turned back to its normal shape and state immediately, was ready to realize along with each goes on foot the circulation of subsiding again and reducing, to cool off footwear continuously and to be its ventilation.By this way, air constantly from the top of insert to the bottom cycle of insert, vice versa, this helps to prevent moisture accumulation and helps the cooling pin.
Should be appreciated that other shapes also can provide the function of domed shape structure 22, for example taper shape, piece shape and different shape and size, volume reverse or forward still are within the scope of the present invention.Illustrate and do not mean that any specific shape or structure for specification and accompanying drawing are limited by any way.
Insert 10 forms by this way,, has air-gap or foamed material 18 between upper strata 14 and bottom 12 that is.The plastics manufacturing of preferred bottom in the former that is formed on insert.Between two-layer, exist under the situation of air-gap, after plastic bottom layer forms and under heated state still, the upper strata of joint (interfacing) is heated to forming temperature and is placed on the bottom.Then combining structure is exerted pressure so that it forms and contact the tie point of plastic bottom layer 12.In a preferred embodiment, binding agent puts on tie point to form instant and permanent combination between the upper strata of plastic bottom layer and joint.
In order to make plastic bottom layer 12, sheet material is loaded in the fixture mount.Support is closed with the edge of fixing sheet material and keeps it reliably during processing.Fixture mount with sheet material is placed in the baking oven of high-temperature control, in optimization material hot saturated preferably be placed between two baking ovens.When material reaches its fusing point, so it is reduced on the mould with positive or negative feature.As all parts of this processing, there is multiple mode to finish its each aspect.For example, substitute mobile backing material, can mobile baking oven and mould can replace its position, and mobile material not.Secondly, apply vacuum, move material to die surface tightly.Mould is maintained at 60 stable degree celsius temperature, this be starkly lower than can be up to 180 degrees centigrade traditional fusion temperature, thereby cause more lacking ground section cool time with curing materials.Opening the fan that arranges at the moulding part place solidifies with acceleration.The molded parts of fixture mount pulling leave mould or mould is lowered to realize identical purpose then.From machine, take out molded insert bottom then and repeat this process.This can all finish less than 10 seconds time.For this insert, the cycle can be 60 seconds scope.A plurality of shoe-pads can utilize suitable mould and anchor clamps hot forming simultaneously.
By adding shaping operation simultaneously, sponge layer 18 can be added to shoe-pad 10.Foam 18 (for example Ethyl vinylacetate (ethyl vinyl acetate)) is heated and is arranged on then on the plastics cushion 12.This plastic layer 12 is stayed in the former, so all contact points are reinforced by this mould.Mold is lowered on the yin shaping up body mould, therefore clamps and seal froth bed 18.The heated froth bed 18 that has heat activated binding agent or hot-melt adhesive then is pressed in the tie point of appointment by the air pressure that accurately applies.Simultaneously, the edge of froth bed 18 closely is pressed on the plastics cushion.This processing very accurately is connected in bottom plastic layer 12 securely and as one man with froth bed 18, and spatial operation placed in the middle is provided between levels.Molded molded foam operation in advance and the equipment eliminated in the time of froth bed.Also shortened the total process time of half, and reduced the needs to accurate engagement tool, the instrument of this accurate cooperation does not need when having this processing.
Utilizing the air pressure of controlling to connect these two or more kind materials allows complicated viscosity point to be set up.Air-gap between the function that this maintenance buffering geometry is whole and the accurate control of permission are two-layer.The alignment hold down gag is very difficult and expensive to finish this processing.If there be any not lining up or material thickness variation really, the result can be defective parts.
Plastic web also can be used as lower floor 12.These nets are by ventilative (breathable) material that vacuum dividing plate (barrier) can be thermoformed into Any shape is installed in forming machine.This dividing plate is silicones sheet material preferably, and it can seal net between itself and vacuum, therefore net is drawn in die surface.Other all processing all keep identical.The inventor does not understand can access any other method with the parts that utilize the porous level that this method obtains.For example, injection moulding (injection molding) can molded net, but only on more smooth surface, and for repeatedly molded any product cost is too high such as the needs of footwear.
Above-described technology reduces the molding costs that is generally used for footwear greatly.The low pressure mould is used the aluminium manufacturing usually, and does not need the die set that cooperates.The cost of this mould lacks half and lacks 80%-90% than the injection moulding mold than the cost of typical compacting tool set.Therefore do not need multi-mould satisfy manufacturing purpose and further reduce molding costs than the fast manyfold of typical pressing mold cycle of footwear the cycle time of this technology.Under the situation of foam-molded operation, do not need a whole set of mould and molding equipment at the same time.
Because its shape keeping property, preferred, bottom is the elastomer with high recovery characteristics and very high physical characteristic.The combination that plasticity or thermoplastic urethane (TPU) have these character, comprise the hot formed operational characteristic that the above-mentioned technology of relative usefulness and product can be operated well, for example fabulous " calorific intensity " and very short " shaping window " (forming window).This two specific character is very important, because it makes the shoe-pad can the very fast demoulding and be stretched at entire die parts and side somatotype (undercut) during the demoulding.Its fast return afterwards is to the shape that is shaped and without any adverse consequences.Compare this specific character with injection molding (injection) and reduce molding costs widely, and can make the shape that other technologies can not be made with the price of commericially feasible.The TPU material is squeezed into the sheet size of hope.The thickness that shoe-pad is suitable is 0.5mm, has width and the length of relatively hot forming machine requirement.Sheet material can be sent to the form of spool or sheet material in the hot forming machine.Other material also is suitable, for example block acid amides, polyester, ethylene vinyl acetate resin, alkene, TPO, thermoplastic elastomer (TPE), thermosets and other.Foam and material layer also can be used in this technology.But TPU has the best of breed of technology and physical characteristic and lower cost.Because also to be engineering handle (over engineered) for it, being used for human the use, so it is safe material and do not need substantive test for the use of most of purposes.
There are three kinds of basic hot forming machine types to can be used in execution the present invention.
A) section transmission device (cut sheet shuttle).This equipment utilization has cut into the sheet material of suitable dimension.Material moves around between baking oven and mould then.On the contrary, material can rest on a position and then baking oven and mould on material or material underneath.To compare this machine both economical and fairly simple with other equipment.With this machine also than being easier to control material consumption.Technological flexibility is also very high.Yet potential cycle time and output therefore are restricted.As all types of heat forming equipments, computer-controlled baking oven and machine movement are wished, with control consistency of product and production efficiency.
The rotation hot former.Because material arrives mold station and demoulding station then by baking oven, so this equipment is with the form mobile material of circle.It can carry out more operation in less space.Operation with this equipment such as insert loading or preheated material is easy to carry out.Even can realize a plurality of mold station or molded a plurality of materials of while.Because trafficability characteristic (access) and more space preferably, so can semi-automatic or even full-automation.Upper die and lower die and other equipment can independent operations, so that each layer and insert can be in modes simultaneously or order, loss cycle time with minimum is set up in a machine.
In-line arrangement roll feed (In-line roll-fed).This equipment utilization is through baking oven, pass through the material roller of mould then, and cooling and die-cut then still is in simultaneously roll form.Even remaining material is also rolled automatically after die-cut.Its recirculation is got back in the material then.The advantage of this equipment is speed.Usually be common near ten seconds cycle time.Even the material extrusion process also can combine with this equipment, significantly reduces raw-material cost.This investment cost of equipment is higher than other types equipment and many setting up (set up) and process limitation is arranged.
By inserting various materials and object, can enough single technology make senior product.Ornamental and functional fabric and net can type in molded (in-molded) in shoe-pad or other products.The details of structure and color, sign, function element also can be by molded in the type.This is because hot forming relates to lower pressure and quick material cured.The material that is molded is without undergoing needed high pressure in other technologies.This obtains only little by little being fused into middle pressure the insert of melted material.Therefore, the non-warping or distortion of insert.Specifically, TPU is consistent and freezing rapidly around insert, neatly structure (frame) it, so it is connected as technology by hand.
In addition, during heat forming technology, almost the material of any enhancing insert can both add in the product.By utilizing heat activated binding agent or hot-melt adhesive, insert can be securely connected.In some cases, do not need binding agent.The all material layer can be inserted into for various decorations and functional purpose.Insert can be made in many ways, but preferably they are by identical heat forming technology and device fabrication.This is to make insert mode and because the ability of the uniqueness of the molded very thin parts of hot forming machine often reduces their cost very efficiently.This also makes expense (over head) optimization of former and factory.The insert that is designed to strengthen the countless other types of final products also can be added during manufacture process.Comfortableness, fitting well property (traction), bacterial control, conductivity of heat, structure, decoration, label, impression, temperature control, function adjusting and many other fine finishining details can be inserted by internal mold (in-mold) and solve.
In fact any design or figure can before or after put on material.Can make an addition on the shaping dies with texture (texture) or on the material.Therefore most of plastics can be decorated and can add one or both sides to, the decoration of being wished very much by extrusion molding pellucidly.Drawing or transfer printing also can put on mould so that plastics are picked up (pick up) material before being shaped.Mould and/or material also can be by veinings.When the material hot forming, apply air pressure by the top to it.Mould texture and details will be given material with very high horizontal transfer printing.
Formpiston also can be used for forming the present invention.The advantage of formpiston is to obtain steep side somatotype in final part.This is not allow facile with other molding technique." side somatotype " be combined the product feature that can not realize before making it possible to produce such as the material of TPU.Can aim to be crowded with the buffer element of the object that conforms to profile such as body part exactly can be made by this way at an easy rate.Another advantage of formpiston is that the whole layer of plastics can be molded on insert or the layer.This makes the more tough and tensile and protection insert in the surface of final products.
Because heat forming technology does not need the die set that cooperates, and owing to have outstanding calorific intensity such as the material of TPU, therefore shape and the easy demoulding of parts that before can not the demoulding.And because heat forming technology carries heat with final parts, that therefore assists can be eliminated with undesirable bonding operation.The binding agent that only activates when being heated to specified temp is well suited for for connecting each layer of the present invention.So be limited on the material piece applying of binding agent before the hot forming.This operation can be controlled and automation to heavens, and eliminates the release of Toxic and directly human body exposure.
Form plastic sheet in the shaping dies then by additional parts are placed on simply on them, additional element can be connected in hot formed insert.In most of the cases, heat activated binding agent must be at first on shaping puts on parts in conjunction with plastic sheet.Same thing can be carried out in former, but this element will not carry out over-molded making/encapsulate mould (overmold) in this case, but is connected in plastic sheet simply.
As noted above, second material is can be simultaneously molded and be connected in plastic sheet.This is very useful feature making aspect more comfortable and perceptual ground of the consumer acceptable of plastic sheet.Foam or tissue layer are very important as interface, top layer (skin interface).Utilizing pressure to connect two kinds of material technologies is very important when the assembling final products.Otherwise the tool set and the point-device scantling that need to cooperate will increase cost and the percent defective of final products like this.This will make final products very expensive and infeasible.Especially true with other products that conform to profile to be fit to human region such as the product that conforms to profile of the helmet, protective device.
Except these materials discussed above, shoe-pad can also comprise the non-stretching material that acts on as moderator (moderator), for example, and the nonwoven polyester fiber of the shock loading that can distribute preferably.This moderator also can prevent the densified of bottom domed shape structure periphery.Moderator can be added on any layer, but is arranged to adjacent underlayer.By the careful selection to domed shape, size and thickness, shoe-pad can also be adjusted specially or regulate specific user, with control turn one's hand over, distribution of weight, comfort level and other factors.And, except whole shoe-pad distribution air, also can be distributed in whole shoe-pad such as other configurations of deodorant, sanitizer etc.Under the situation that top layer by the sole shoe-pad does not expose at dome, this element (component) is useful in the hot formed dome in that ethylene vinyl acetate resin is assembled to.
The other materials that can be used in top layer or top layer is chitin (chitin), and it is a kind of material that has with the celluloid same nature, and is soft, biocompatible, can prevent bacterial growth, and easily dyeing to form color graphics at the shoe-pad top.
It is to form every layer material independently that another kind of assembling is selected, with heat activated adhesive coated they, then they are alignd.Insert in the mould this assembly and heating then.Pressure puts on top layer with all laminations tightly together then.Only connect these materials in the place of hope with the viscosity point.Single layer or entire product can be the back perforation to be used for the purpose of aeration or perception.
Find that also multilayer buffer unit of the present invention can superpose or form layer structure to increase pooling feature, particularly in other are used.Stack or embed arrange in utilize a plurality of buffer units can increase the integrated buffer ability widely, and provide low-cost possibility to very complicated and expensive material.
