The specific embodiment
Below with reference to drawing, according to its best example explanation the present invention.
Fig. 1 is the exploded perspective view of the 1st example of drying mould of the present invention, and Fig. 2 A and Fig. 2 B represent to see from its divisional plane side the front view and the sectional side view of the drying mould shown in Fig. 1 respectively.
The drying mould 1 of this example is to be used for the fiber pad body of the moisture state that obtained by the paper pulp modulus method is carried out drying.Drying mould 1 is made of fiber pad body resettlement section (being designated hereinafter simply as the resettlement section) 10 and manifold portion 20.Resettlement section 10 has the piece 11 of cubic and the tabular flange 12 that extends from the tripartite along continuous straight runs of these piece 11 upper ends.On piece 11, that the method with regulation of being concaved with is shaped, with the concavity drying section 13 of vertical half shape that obtains after chimeric of the fiber pad body of moisture state, in this drying section 13, can accommodate the fiber pad body.The top 12a of flange 12 is flat condition, and 12a becomes the divisional plane (involutory surface) of drying mould 1 above this.The surface of the drying section 13 in the drying mould 1 of this example, gauze is not copied in configuration.Fiber pad body resettlement section 10 can be made of the metal of aluminium etc.On piece 11, dispose the not shown heater that the drying section 13 of drying mould 1 is heated usefulness again.
Manifold portion 20 be a kind of can with the box structure of the chimeric cubic in resettlement section 10.On the sidewall of manifold portion about 20, be equipped with respectively the inside of manifold portion 20 and the attraction mouth 21 of external communications.On the face of manifold portion 20 and resettlement section 10 butts, dispose containment member 22.Utilize sealing member 22, can keep airtight conditions in the hollow chamber described later, can prevent that the attraction efficient in the hollow chamber from reducing.
In case resettlement section 10 is chimeric with manifold portion 20, then forms hollow chamber 23 between the two.Hollow chamber 23 by the vent passage 15 of joint-cutting shape described later, is communicated with the drying section 13 of resettlement section 10 simultaneously by attracting mouth 21 and external communications.
Under the state that resettlement section 10 and manifold portion 20 is chimeric, engage by the clip 14 that has on the ring 24 that will have in the manifold portion 20 and the resettlement section 10, releasably resettlement section 10 is fixed in the manifold portion 20.Because the shape of the formed body that the shape of the drying section 13 in the resettlement section 10 is root a tree names should be made and different, therefore, its advantage is by resettlement section 10 releasably is fixed in the manifold portion 20, when changing the manufacturing kind, as long as change resettlement section 10, do not need the shape of every kind of formed body of root a tree name to make drying mould integral body.
In this example, use 2 drying moulds 1 as depicted in figs. 1 and 2, under the fiber pad body with moisture state is housed in state in the die cavity that is formed by 2 drying sections 13 that divisional plane separately is involutory mutually, this fiber pad body is carried out drying.
In drying mould 1, the part corresponding with trunk of the fiber pad body in drying section 13 centers on the vent passage 15 that its trunk is formed with a plurality of joint-cutting shapes of general horizontal direction extension.Vent passage 15 is formed with a plurality of with the interval of stipulating on the above-below direction of drying section 13.Vent passage 15 can make drying section 13 be communicated with hollow chamber 23, thus, can carry out the steam exhaust not causing under the state of steam outburst, can form rib on the outer surface of the formed body of given size shape.Again, the both ends of vent passage 15 have formed the form that does not arrive described involutory surface, thus, by the handing-over that attracts to copy the fiber pad body between the paper drying mould by compressed-air actuated removing behind this air channel and air with in the formed body demoulding of drying mould, can restrain from the air of involutory surface and leak.
The vent passage of joint-cutting shape can be used wire discharge cutter and laser etc., form easily and at short notice.Particularly at the mouth neck portion that is provided with the threaded portion with implemented the part with complicated shape of the trunk etc. of processing such as decorative pattern, also can form easily.
From the viewpoint that improves the formed body outward appearance and the viewpoint of the processability of being convenient to vent passage and maintenance etc., the width of the vent passage of joint-cutting shape (drying section 13 lip-deep width) is advisable with 0.05～5mm, and 0.1～2mm is better, preferably 0.1～0.5mm.Particularly when the width of vent passage surpasses 5mm, because of generation is concavo-convex easily on the surfaces externally and internally of formed body, so be difficult to expeditiously the surfaces externally and internally of formed body is applied.
Be set at a at width with drying section 13 lip-deep vent passage, when the width of the vent passage on drying section 13 back sides (with the subtend face of manifold portion 20) is set at b, should be a≤b, promptly, the viewpoint of stopping up from the vent passage that prevents to cause and the viewpoint that further improves exhaust efficiency and drying efficiency because of pulp powder etc., the section shape of vent passage depth direction is straight line or annulus is cut into the shape of fan-shaped preferably.Particularly be advisable with a＜b.In this occasion,, be advisable particularly 10～30 from further improving the viewpoint of exhaust efficiency and drying efficiency with b/a=1.5～40.
Again, (aridity is in case difference occurs because of the different parts of formed body from the homogenization of exhaust efficiency and aridity, just might make formed body distortion) viewpoint set out, be advisable particularly 2～70% with 0.5～70% with respect to the percent opening of the vent passage 15 of the joint-cutting shape of drying section 13 areas.In addition, from the maintaining viewpoint of the release property and the model of formed body, drying section 13 and involutory surface preferably carry out the coating of polytetrafluoroethylene (PTFE) etc.
On drying section 13, except the vent passage 15 of joint-cutting shape,, be preferably formed as many passages 16 in order to improve drying efficiency.
If adopt the drying mould 1 of this example, then can not cause the steam outburst, and, on the formed body inner face with the corresponding part in formation rib position depression (recess) can not appear, can on the outer surface of formed body, form the tiny joint-cutting of required width.Again, because the both ends of vent passage 15 have formed the form that does not arrive involutory surface, therefore, in the manufacture process of formed body, by the handing-over that attracts to copy the fiber pad body between the paper drying mould by compressed-air actuated removing after this vent passage 15 and air with in the formed body demoulding of drying mould, can restrain from the air of involutory surface 12a and leak, can stably make formed products.
Below, on one side in conjunction with drawing, its best example of root a tree name is made an explanation to molded article production method of the present invention on one side.Fig. 3 A～Fig. 3 D is the diagrammatic sketch of the summary operation of the molded article production method of this example of employing, and Fig. 3 A is the injection dehydration procedure of pulp material, and Fig. 3 B is that core inserts operation, and Fig. 3 C is the pressurizing and dehydrating operation, and Fig. 3 D is a stripping process.In Fig. 3 A～Fig. 3 D, for for simplicity, simplifications such as the structure of paper matrix and shape will be copied.
At first, as shown in Figure 3A, involutory by a pair of composite die 4,5 that will have vent passage 40,50, from the upper opening portion of copying paper matrix 7 of the die cavity 6 of the corresponding shape of profile of the formed body that is formed with in inside and should be shaped, will be with paper pulp as the injection of pressurizeing of the slurry (hereinafter referred to as pulp material) of main body.The pressurization of pulp material is injected for example can adopt force lift.The pressure that the pressurization of pulp material is injected is advisable with 0.01～5MPa, and 0.01～3MPa is better.
In case when the amount of slurry of the pulp material in the injection die cavity 6 reaches ormal weight, just begin to attract dehydration by the pulp material after the described vent passage 40,50.Thus, the moisture in the pulp material is discharged to the outside of copying paper matrix 7, simultaneously paper pulp fiber is deposited in the inner face (copying the inner face of gauze) of die cavity 6, at the inner face of die cavity 6, forms the fiber pad body 8 of the hollow that is made of pulp layer.
The paper pulp fiber that above-mentioned pulp material is used can adopt common material used in the manufacture method of this pulp mold formed body.Pulp material both can only be made of paper pulp fiber and water, also can be on the basis of paper pulp fiber and water, add the powder of thermoplastic synthetic resin of inorfil, polyolefin etc. of inorganic matter, glass fibre and the carbon fiber etc. of talcum powder and kaolin etc. or the composition of fiber, non-timber or phyteral fiber, polysaccharide etc. again.The use level of these compositions is advisable with 1～70 weight % with respect to the total amount of paper pulp fiber and this composition thereof, particularly 5～50 weight %.Pulp density in the pulp material is advisable with 0.1～5 weight %, particularly 0.3～3 weight %.
After the fiber pad body that has formed the regulation wall thickness, shown in Fig. 3 B, die cavity 6 is attracted decompression, will have elasticity simultaneously, core 9 capable of expansion and contraction and that be hollow form inserts in the die cavitys 6.The effect of core 9 is equally to expand by meteorologic balloon in die cavity 6, and the fiber pad body 8 of the moisture state that will be made of pulp layer is urged to the inner face of die cavity 6, gives the interior shape of die cavity 6.For this reason, good urethane, fluorine such as core 9 employing TENSILE STRENGTH, bounce-back property and retractility are that rubber, silicon are the sticking up property film formation of rubber or synthetic rubber etc.
Secondly, shown in Fig. 3 C, in core 9, supply with pressure fluid, core 9 is expanded, utilize the core 9 after expanding, the fiber pad body 8 of moisture state is urged to the inner face of die cavity 6.So the core 9 after this fiber pad body 8 is inflated is pressed in the inner face of die cavity 6, when the interior shape with die cavity 6 is replicated in this fiber pad external surface, further dewaters again.Like this, owing to the fiber pad body 8 of described moisture state is pressed in the inner face of die cavity 6 from the inside of die cavity 6, therefore,, also can be accurately the interior shape of die cavity 6 be replicated on the outer surface of this fiber pad body 8 even die cavity 6 inner faces is complex-shaped.And, different with the manufacture method of traditional paper pulp mould, because of not needing to use bonding process, so on the fiber pad body that obtains, do not have the seam and the heavy section that cause because of applying.Its result not only can improve the intensity of the formed body that finally obtains, but also can make image appearance good.As the pressure fluid that makes core 9 expansion usefulness, for example, can use compressed air (adding hot-air), oil (adding deep fat) and other various liquid.Supply with the pressure of pressure fluid and be advisable, particularly 0.1～3MPa with 0.01～5MPa again.
When the dehydration of fiber pad body 8, also can aforesaid core 9, and use instead to the inside to fiber pad body 8 is blown into air, with the inner face pushing of fiber pad body 8 to die cavity 6, make 8 dehydrations of fiber pad body, and give the interior shape of die cavity 6 to fiber pad body 8.
When on the outer surface of the described fiber pad body 8 that is constituting by pulp layer, fully duplicated the interior shape of die cavity 6 and with the dehydration of this fiber pad body to the moisture content of regulation, shown in Fig. 3 D, the pressure fluids in the core 9 are emitted.So core 9 automatically shrinks, and reverts to original size.Then, from the die cavity 6 interior cores 9 that take out after shrinking, open and copy paper matrix 7, the fiber pad body 8 that will have the not drying regime of regulation moisture content takes out.The fiber pad body of the not drying regime after the taking-up enters down and pushes drying process together.
Is that method according to shown in Fig. 4 A～Fig. 4 G is carried out from copying the paper dehydration procedure to dividing a word with a hyphen at the end of a line of pushing drying process.Promptly, shown in Fig. 4 A, on a side who carries out the compressed air removing from the described vent passage 40 of composite die 4, described vent passage 50 by composite die 5, the fiber pad body 8 of drying regime is not carried out vacuum suction, shown in Fig. 4 B, from composite die 4 demouldings, fiber pad body 8 is accumulated in the composite die 5 in the outer surface of fiber pad body 8 half.And, shown in Fig. 4 C, will accumulate this composite die 5 that fiber pad body 8 is arranged, move in the place ahead of a side of used drying mould 1 in the pushing drying process, makes both opposed.Then, shown in Fig. 4 D that both involutory surfaces is involutory, fiber pad body 8 is housed in two models.And, shown in Fig. 4 E,,, remove by 50 pairs of compressed air of vent passage, 8 demouldings of fiber pad body from composite die 5 sides from drying mould 1 side, undertaken on the side of vacuum suction by 15 pairs of fiber pad bodies of described vent passage.And, fiber pad body 8 is attracted to drying mould 1 side, be housed in the model 1 after, composite die 5 is kept out of the way.Then, shown in Fig. 4 F, make and accommodate half move of fiber pad body 8 with drying mould 1 corresponding another drying mould 1, with involutory surface 12a, 12a that these two drying moulds 1,1 are involutory, whole fiber pad body 8 is housed in both.The device that relevant this operation of dividing a word with a hyphen at the end of a line is used will describe in detail in the back.
Below, with reference to Fig. 5 A～Fig. 5 D the pushing drying process is made an explanation.In addition, in Fig. 5 A～Fig. 5 D, for for simplicity, with simplifications such as the structure of drying mould and shapes thereof.At first, shown in Fig. 5 A,, the fiber pad body 8 of drying regime not is housed in the die cavity that is formed by 2 drying sections 13 by the divisional plane of 2 drying moulds 1,1 is involutory mutually.Two drying moulds 1 are heated to set point of temperature in advance.
Then, shown in Fig. 5 B, by attracting mouthful (not shown), from its inside to the outside drying mould 1 is attracted decompression, the bag shape core 3 with hollow inserts in the fiber pad body 8 simultaneously.Core 3 can adopt have by with machine hand's preface in the material of used material identical characteristics constitute.
Secondly, shown in Fig. 5 C, to core 3 in, supply with pressure fluid, core 3 is expanded, utilize the core 3 after the expansion, the fiber pad body 8 of drying regime not is urged to the inner face of drying section 13.Core 3 after fiber pad body 8 is inflated is pressed in the inner face of drying section 13, by vent passage 15, moisture in the fiber pad body 8 is under the state that does not cause the steam outburst, discharge to the outside as steam, fiber pad body 8 is carried out drying, and the shape copying of drying section 13 that will comprise vent passage 15 shapes simultaneously is on the outer surface of fiber pad body 8.And, on the outer surface of the trunk of dried fiber pad body (formed body), form the tiny rib of required width.Like this owing to, fiber pad body 8 is pressed on the drying section 13 to the outside from the inside of fiber pad body 8, therefore, even drying section 13 is complex-shaped, also can high drying efficiency ground with fiber pad body 8 dryings.And, accurately with the shape copying of the inner face of drying section 13 on the outer surface of fiber pad body (formed body) 8.As the pressure fluid of core 3 expansion usefulness, for example, can use compressed air (adding hot-air), oil (adding deep fat) and other various liquid.Supply with the pressure of pressure fluid and be advisable, particularly 0.1～3MPa with 0.01～5MPa again.
After the moisture content that fiber pad body 8 intensive dryings are extremely stipulated, shown in Fig. 5 D, emit the pressure fluid in the core 3, core 3 is dwindled.Then,, open two drying moulds 1,1 again, dried fiber pad body (formed body) 8 is taken out from the fiber pad body 8 interior cores 3 that take out after dwindling.
Like this, if adopt the molded article production method of this example, just can on the outer surface of formed body trunk, have a plurality of thin ribs, stable and produce on the formed body inner face and the corresponding part in formation joint-cutting position expeditiously and not have the formed body that caves in.
Fig. 6 represents an example of formed body of the present invention.In the figure, symbol 8 is expressed as body.
As shown in the drawing, formed body 8 is a kind of diameter of mouth neck portion 80 columnar flasks less than trunk 81 diameters.On the outer surface of the trunk 81 of formed body 8,, be formed with a plurality of around the tiny ribs (raised line) 82 of the horizontally extending width of trunk along the vertical direction with predetermined distance.From obtaining the viewpoint of reliable clamping, the rib that on the outer surface of formed body of the present invention, forms, its height is advisable with 0.05～2mm, and 0.1～1.0mm is better.Again, if the height of rib is too high, when then implementing to apply on formed body 8, rib becomes obstacle, produces uncoated part, or at the residual coating of foundation portion of rib, makes coat inhomogeneous, or the coating agent permeates easily, or destroys rib easily.Again, the width of rib is advisable with 0.05～5mm, and 0.1～2mm is better.From the intensity that improves clamping, adds when guaranteeing the clamping formed body etc., be advisable with 3～50mm in the interval of rib, and 5～25mm is better.
Again, because the trunk 81 of formed body 8 is high strength objects of strengthening with rib 82, therefore, even in use, trunk 81 also is not easy depression, and conformality is good, and is easy to use.Again, for example, even formed body 8 enter the manufacturing processing line that comprises content-filled streamline etc., with the clamping device of carrying device etc. carry out clamping, with content-filled in this formed body or loading onto the occasion of lid thereafter, because the rib 82 that forms on trunk 81 has the function of on-slip, improved controlling property, therefore, be not easy to cause conveyance error etc., can not cause obstacle making processing line.And because on this formed body 8, mouth neck portion 80, trunk 81 and bottom 83 all do not have seam, and it is integrally formed to add mouth neck portion 80, trunk 81 and bottom 83, and therefore, aesthetic appearance is also good.Formed body 8 for example can be made by the above-mentioned molded article production method with drying mould 1.
Fig. 7, Fig. 8 A and Fig. 8 B represent the 2nd example of drying mould of the present invention.In addition, in these figure, to the general part of aforementioned the 1st example, the mark prosign omits its explanation.Therefore, for there not being the part that specifies, suitable with the explanation in the aforementioned example.
As shown in Figure 7, in the drying mould 1 ' of this example, the corresponding part of the trunk with formed body in the drying section 13 of concavity is provided with along the vent passage 15 of a plurality of joint-cutting shapes of its above-below direction extension.Vent passage 15 forms a plurality of with the interval of stipulating around drying section 13.Say at length that again vent passage 15 makes drying section 13 be communicated with hollow chamber 23.
If adopt the drying mould 1 ' of this example, then the drying mould 1 with the 1st example is the same, can not cause the steam outburst, and can on the formed body inner face with the corresponding part in formation rib position depression (recess) not appear, can on the outer surface of formed body, form the tiny joint-cutting of required width.Again, because the both ends of vent passage 15 have formed the form that does not arrive involutory surface, therefore, in the manufacture process of formed body, in the handing-over that attracts to copy the fiber pad body between the paper drying mould by compressed-air actuated removing and air with in the formed body demoulding of drying mould, can restrain from the air of involutory surface and leak, can stably make formed products.
Fig. 9 is another example of expression formed body of the present invention.In the figure, to the general part of formed body shown in Figure 68, the mark prosign omits its explanation.Therefore, for there not being the part that specifies, suitable with the explanation in the aforementioned example.Formed body 8 be a kind of around the trunk 81 with the interval of regulation, be formed with along the vertical direction the structure of the tiny a plurality of ribs 82 of the width that extends.Formed body 8 is the same with formed body 8 shown in Figure 6, and the conformality height during use is not easy to cause conveyance error that is caused by carrying device etc.Again and since within it on the face with rib 82 corresponding parts depression not, therefore, can apply expeditiously.Formed body 8 for example, in the manufacture method of above-mentioned formed body, can adopt the drying mould 1 of drying mould 1 ' to replace aforementioned the 1st example of the 2nd example, make.
The present invention is not limited to aforementioned example.For example, aforementioned example is to form rib 82 on the trunk 81 of formed body 8, but also can not adopt this form, but as the drying mould 1 ' of the 3rd example shown in Figure 10, the corresponding position of trade mark sticking part (closing portion's corresponding position to call trade mark label in the following text) 13a with trunk formed body on drying mould in advance forms vent passage 15a, forming vent passage 15b with the corresponding position of mouth neck portion (to call the mouth neck portion corresponding position in the following text) 13b, and forming vent passage 15c, at the mouth neck portion of hollow forming body with corresponding position, bottom (to call the bottom corresponding position in the following text) 13c, rib is formed on trade mark sticking part and bottom.Particularly when mouth neck portion forms rib, also its rib can be used as the rib that prevents the chimeric usefulness that lid unclamps.In this occasion, for example, the preferably foregoing a≤b of width of slit a, the b of a certain vent passage＜for example, the vent passage (with reference to Fig. 7) of the vertical formation on the corresponding position with trunk, with the corresponding position of mouth neck portion on the vent passage (with reference to Figure 10) that forms.As an example, Figure 11 represents state that the width of slit a of the vent passage 15b of mouth neck portion corresponding position 13b, b are set at a＜b.
Again, drying mould of the present invention is preferably as aforementioned example, and the end that forms vent passage does not arrive the such form of involutory surface, but also can form for example drying mould 1 ' of the 4th example shown in Figure 12, Figure 13 A and Figure 13 B.That is, the drying mould 1 ' shown in these figure has formed the shape that an end side of vent passage 15 is arrived involutory surface 12a, and vent passage 15 is connected with the through hole 12b that forms on flange 12, this involutory surface 12a is connected.The drying mould 1 ' of this example is in the manufacture process of formed body, as shown in figure 14, be that model under the state that each involutory surface 12 is involutory, after involutory (though be drying mould in the figure, when the fiber pad body handing-over of carrying out moisture state, become and copies paper matrix.) in the end of vent passage 15 is configured to mutually the form of subtend not uses.Thus, in the handing-over that attracts to copy the fiber pad body between the paper drying mould by compressed-air actuated removing and air with in the formed body demoulding of drying mould, can restrain from the air of involutory surface 12a ' and leak, can stably make formed products with near the rib of arrival involutory surface 12a.Again,, therefore, can further improve drying efficiency, manufacture body more expeditiously owing to strengthened the length of the vent passage 15 on the drying section 13.
Again, aforementioned example is 2 involutory uses of drying mould, but but the also shape of root a tree name formed body only use 1 drying mould or the drying mould more than 3 be used in combination.
Again, the drying section of the drying mould in the aforementioned example is concavity, but but the also shape of the root a tree name formed body that should be shaped is made convex with drying section.
Again, also can be at the back side of the drying mould in the aforementioned example promptly, on the drying mould and the face face opposition side that forms drying section, fixing with being equipped with behind the tabular component butt of heater of electrothermal heater etc., with this tabular component drying mould is heated.Thus, because heat process manifold portion 20 and fiber pad body resettlement section 10 with this tabular component generation, be applied to indirectly on the fiber pad body, therefore, with heater is installed in the member that directly contact with this fiber pad body is, occasion on the fiber pad body resettlement section 10 compares, be not easy to produce the temperature inequality, can further carry out uniform drying the fiber pad body.Again, the thermal capacity by abundant increasing fiber pad body resettlement section 10 is not easy to produce the temperature inequality more.Because of being not easy to cause that the temperature of drying mould reduces, so these characteristics are particularly useful for many fiber pad bodies are carried out the occasion of continuous drying.For example, the fiber pad body is seated in the drying mould that is set at 200 ℃ after soon the temperature of this drying mould descend, should be to be advisable below 20 ℃, better below 10 ℃.
Again, the present invention is as aforementioned example, though be particularly useful for comprising and 2 composite dies be combined to form the manufacture method of copying paper matrix, pulp material being injected the pulp material of the operation of copying paper in this die cavity of copying paper matrix, but except this manufacture method, for example, also applicable to copying the manufacture method that paper matrix immerses in the reservoir fill pulp material, supplies with pulp material in this copies the die cavity of paper matrix.Again, also applicable to the composite die shape that will have vent passage copy paper matrix, it is copied paper towards above be configured in, will be at least be provided in around the close shape of the housing liquid ground of copying paper this copy on the paper matrix, copy by this paper and this housing form the reservoir of filling pulp material, then the pulp material with ormal weight be filled in this reservoir, by this vent passage attraction pulp material, copying the manufacture method that is formed into body on the paper.
Below, the divide a word with a hyphen at the end of a line device of usefulness of the fiber pad body that illustrated among Fig. 4 A～Fig. 4 G is made an explanation.Figure 15～Figure 22 is the manufacture method of expression formed body of the present invention and the ideograph that suitable best manufacturing installation is seen from above thereof.
As Figure 15～shown in Figure 20, manufacturing installation 100 has the 2nd metal pattern of using as drying mould 120 that the conduct that is made of a pair of composite die A, B is copied the 1st metal pattern 110 that paper matrix uses and is made of a pair of composite die C, D.Composite die A, B are corresponding with aforesaid composite die 4,5, and composite die C, D are corresponding with aforesaid drying mould 1,1.The 1st metal pattern 110 forms the die cavity with the corresponding shape of formed body profile that should be shaped by with the mutual involutory mold closing that carries out of the divisional plane of composite die A, B.The 2nd metal pattern 120 also is same, by with composite die C, D mold closing, forms and the identical shaped die cavity of above-mentioned die cavity.Again, on composite die C, the D of the 2nd metal pattern 120, dispose the heater of heater etc., can be heated to set point of temperature.The concavity shape of composite die A inner face is identical with the concavity shape of composite die C inner face, and again, the concavity shape of composite die B inner face is also identical with the concavity shape of composite die D inner face.Under with the composite die C of composite die A, the B of the 1st metal pattern 110 and the 2nd metal pattern 120, state behind the D mold closing,, form the oral area 111,121 that is communicated with above-mentioned die cavity on the top of each metal pattern 110,120.
In manufacturing installation 100, composite die A, C and D should have the holding device of formed body at least.When making pulp mold formed body, composite die A～D has the holding device that also can be used as in the formed body of the dewater unit function of formed body.This holding device is made of intercommunicating pore and suction device thereof.
Composite die A, the C of each My World in two metal patterns 110,120 are fixed on the same one side of slip stereotype plate 130.In order to make composite die A, C short transverse separately parallel, separately rear side is fixed on the slip stereotype plate 130 with the short transverse of slip stereotype plate 130.Slip stereotype plate 130 is by the carriage of bearing etc., will with the face of the stationary plane opposition side of composite die A, C, be fixed on the medial surface of the 1st side plate 131 slidably, can be along the width reciprocating motion of composite die A, C.
Composite die B, the D of the opposing party separately in two metal patterns 110,120 individually is fixed on respectively on the face of the same side of 2 movable stereotype plates 132,133 separately.Composite die B, D rear side separately is fixed on respectively on the movable stereotype plate 132,133.Again, the interval of composite die B, D be fixed on slip stereotype plate 130 on composite die A, C between the interval identical.Thus, the divisional plane of the divisional plane of composite die A and composite die B is the subtend shape, and same, the divisional plane of the divisional plane of composite die C and composite die D is the subtend shape.Each movable stereotype plate 132,133 is respectively by a pair of pull bar 134,135 supportings.The two ends of each pull bar 134,135 are fixed on the 1st above-mentioned side plate 131 and stand on the 2nd side plate of establishing 138 with the 1st side plate 131 subtend shapes.
On the lateral surface of the 2nd side plate 138, hydraulic cylinder 136,137 is housed.The piston rod 136 ' of each hydraulic cylinder 136,137,137 ' front end are fixed on the face of on each movable stereotype plate 132,133 and stationary plane opposition side composite die B, D.And by the action of hydraulic cylinder 136,137, movable stereotype plate 132,133 moves along pull bar 134,135, and thus, composite die B, D can move back and forth along being fixed on the direction with divisional plane quadrature composite die A, C on the slip stereotype plate 130.Because manufacturing installation 100 has so structure, therefore, composite die A, the B of the 1st metal pattern 110 can carry out the mold closing die sinking.Equally, composite die C, the D of the 2nd metal pattern 120 can carry out the mold closing die sinking.
And, in manufacturing installation 100, by moving of slip stereotype plate 130, can make composite die A that is fixed on the 1st metal pattern 110 on the slip stereotype plate 130 and the composite die D subtend shape ground that is fixed on the 2nd metal pattern 120 on the movable stereotype plate carry out the mold closing die sinking, thus, can under the state that the fiber pad body is remained in the composite die, carry out the handing-over of fiber pad body to the 2nd metal pattern from the 1st metal pattern.
The manufacturing installation 100 that adopts structure like this is manufactured the method for body and the action of manufacturing installation 100 describes together.At first, as shown in figure 15, slip stereotype plate 130 is moved, make it be in the position shown in this figure with device specifies.Then, make hydraulic cylinder 136,137 actions, composite die B, D are released, in composite die B and composite die A mold closing, composite die D and composite die C mold closing.When the running beginning,, do not load any article in the inside of the 1st and the 2nd metal pattern 110,120.In the running, be provided with any article of filling in the inside of the 1st metal pattern 110, but, be filled with the fiber pad body 139 of the high saturation state that is shaped by the 1st metal pattern 110 in the inside of the 2nd metal pattern 120.For convenience's sake, below the situation in relevant manufacturing installation 100 runnings is made an explanation.
Then, pulp material supply pipe (not shown) is descended from the top of the 1st metal pattern 110, its front end is connected with oral area 111.Under this state, make injection pump (not shown) action, the supply source (not shown) of pulp material from pulp material injected in the die cavity of the 1st metal pattern 110.When injecting pulp material, by the intercommunicating pore of composite die A, B, attract composite die A, B from the outside, make decompression in the die cavity.Thus, in the moisture in attracting pulp material, paper pulp fiber is deposited in the inner face of die cavity.After the pulp material with ormal weight injects die cavity, stop the injection of pulp material, to attracting dehydration in the die cavity.Its result, paper pulp fiber is stacked on the die cavity inner face of the 1st metal pattern 110, forms the fiber pad body of saturation state.Because the fiber pad body after so being shaped becomes high saturation state, therefore, want to carry out 110 die sinkings of the 1st metal pattern, use outside carrying device to take out, be transferred to just unusual difficulty of next process (secondary operations operation) in the die cavity.But, as described later, in the present invention, owing to being under the state that the fiber pad body is remained in the composite die, carrying out the handing-over of fiber pad body to the 2nd metal pattern 120 from the 1st metal pattern 110, therefore, can easily carry out secondary operations to operability bad fiber pad body like this.
When using the 1st metal pattern 110 to carry out the shaping of fiber pad body, in the 2nd metal pattern 120, the fiber pad body 139 of filling is implemented secondary operations.The secondary operations of this example is exactly the pressurized, heated dehydration of fiber pad body.About the content of this pressurized, heated dehydration, because of with aforementioned the same, its explanation of Therefore, omited.
After the fiber pad body pressurized, heated dehydration in shaping of the fiber pad body in the 1st metal pattern 110 and the 2nd metal pattern 120 finishes, described pulp material supply pipe (not shown) is risen, from 110 separation of the 1st metal pattern.Meanwhile, in the 2nd metal pattern 120, in the die cavity of the 2nd metal pattern 120, the core that uses the pressurized, heated dehydration is taken out.
Secondly, only attract the composite die A on the 1st metal pattern 110, the fiber pad body after being shaped is remained in the composite die A.Meanwhile, only attract the composite die C on the 2nd metal pattern 120, will remain in the composite die C through the formed body that the pressurized, heated dehydration obtains.Under this state, make hydraulic cylinder 136,137 actions, as shown in figure 16, composite die B, D are retracted, in composite die B and composite die A die sinking, composite die D and composite die C die sinking.Its result, as shown in the drawing, the fiber pad body 139 that is shaped with the 1st metal pattern 110 becomes it, and half is maintained at the state in the composite die A longitudinally.Again, half is maintained at the state in the composite die C longitudinally also to become it with the 2nd metal pattern 120 formed body 140 that dehydration obtains through pressurized, heated.
Under the state that fiber pad body 139, formed body 140 is remained on respectively in each composite die A, C, slip stereotype plate 130 is moved along direction shown in the arrow among Figure 17, make composite die A be in composite die C and move preceding position.Thus, the divisional plane of the composite die D of the divisional plane of composite die A and the 2nd metal pattern 120 is the subtend shape.The result that slip stereotype plate 130 moves, the composite die C that will keep through the formed body 140 that the pressurized, heated dehydration obtains is as shown in the drawing, moves on the processing line of next process (for example goods discharge operation).
Be under the state of subtend shape at the composite die A of the 1st metal pattern 110 and the composite die D of the 2nd metal pattern 120, as shown in figure 18, make hydraulic cylinder 137 actions, composite die D is released, with composite die D and composite die A mold closing, again fiber pad body 139 is seated in the inside of these composite dies.Under the state of its mold closing, stop attraction to composite die A, remove the hold mode of fiber pad body 139.Meanwhile, carry out the attraction of composite die D, fiber pad body 139 is remained in the composite die D.During this action, formed body 140 directions that are maintained at composite die C in of goods taking-up arm 141 on the processing line that moves to next process with suction device are close.
Secondly, make hydraulic cylinder 137 actions, D retracts with composite die, with the composite die A and the composite die D die sinking of mold closing state.As previously mentioned, fiber pad body 139 does not remain in the composite die A, but is maintained in the composite die D, so by die sinking, fiber pad body 139 is transferred to composite die D side.Thus, finish fiber pad body 139 from the handing-over of composite die A to composite die D.During this action, as shown in figure 19, goods take out the attraction position and formed body 140 butts that remain in the composite die C of arm 141, and formed body 140 absorption are kept.Meanwhile, stop attraction, remove the hold mode of formed body 140 composite die C.Then, goods take out arm 141 to be separated from composite die C, takes out formed body 140 from composite die C, is expelled to next process.
Finish after the aforesaid handing-over, as shown in figure 20, slip stereotype plate 130 is returned to the preceding state that moves, the composite die A that has removed fiber pad body 139 hold modes is returned move preceding position, be the subtend shape with composite die B.Meanwhile, return take out composite die C behind the formed body 140 to position before moving, be the subtend shape with the composite die D that maintains fiber pad body 139 states.Then, make hydraulic cylinder 136,137 actions, composite die B, D are released, composite die B and composite die A mold closing.Meanwhile,, again fiber pad body 139 is seated in the inside of these composite dies, recovers state shown in Figure 15 composite die D and composite die C mold closing.Then, carry out above-mentioned action repeatedly.
If adopt above-mentioned example, then can not apply mechanical deformation force to the fiber pad body, can not cause unnecessary deformation.Do not worry dislocation between incidental when using outside carrying device, fiber pad product and the metal pattern again.And, compare with the occasion of using outside carrying device, can reduce the die sinking amount, make equipment miniaturization, and can reduce process number, shorten the manufacturing cycle.
Below, with reference to Figure 21 A, Figure 21 B and Figure 22 another example is described.In these examples, only to making an explanation with aforesaid example dissimilarity, for the part that is not specifically noted, the detailed description of having done in the aforesaid example suits to be used in.Again, in Figure 21 A, Figure 21 B and Figure 22, the member place identical with Figure 15～Figure 20 is marked with prosign.
The manufacturing installation 100 of the example shown in Figure 21 A and Figure 21 B is a kind of forming machine of tandem.Figure 21 A is equivalent to the state shown in Figure 15 in the aforesaid example, and Figure 21 B is equivalent to the state shown in Figure 16 in the aforesaid example.Again, the state of representing with the dotted line among Figure 21 B is equivalent to state shown in Figure 17.The manufacturing installation 100 of this example has two pairs the 1st metal patterns 110 and the 2nd metal pattern 120 respectively, in one-period, can carry out the shaping of 2 fiber pad bodies and the secondary operations of fiber pad body (pressurized, heated drying).And, in the manufacturing installation 100 of this example, also can be by slip stereotype plate 130,130 ' move, make and be fixed on this slip stereotype plate 130, the composite die A of the 1st metal pattern 110 on 130 ' be fixed on movable stereotype plate 133, the composite die D of the 2nd metal pattern on 133 ' is the subtend shape, and by movable stereotype plate 133,133 ' with respect to slip stereotype plate 130, the mold closing die sinking is carried out in 130 ' reciprocating motion, thus, the fiber pad body is being remained under the state of composite die, carrying out the handing-over of fiber pad body to the 2nd metal pattern 120 from the 1st metal pattern 110.
The composite die C of the composite die A of the 1st metal pattern 110 and the 2nd metal pattern 120 is fixed on the slip stereotype plate separately, and this is the same with aforesaid example.But in this example, use 2 slip stereotype plates 130,130 ', on the slip stereotype plate 130 that a side composite die A and composite die C is fixed on a side, on the slip stereotype plate 130 ' that the opposing party's composite die A and composite die C is fixed on the opposing party.And 2 composite die A are fixed on the stereotype plate 130 of respectively sliding, 130 ' according to its back side with being the subtend shape.2 composite die C also are same.Each slide stereotype plate 130,130 ' carriage by bearing etc. are fixed on the fixed head 142 slidably, can move back and forth along the width of composite die A, C.
Composite die B, the B of the 1st metal pattern 110 is separately fixed on the movable stereotype plate 132,132 '.Equally, composite die D, the D of the 2nd metal pattern 120 are separately fixed on the movable stereotype plate 133,133 '.With the other end of an end and the 2nd side plate 138, the 138 ' linkage 143,144 after fixing, be fixed on the face of on the movable stereotype plate 132,133 and stationary plane opposition side composite die B, D.Two linkages 143,144 fulcrum separately partly is fixed on the supporting member 144a.Movable stereotype plate 132 and fixed head 142 are by a pair of pull bar 134 supportings.Equally, movably stereotype plate 133 is by pull bar 135 supportings.And fixed head 142 is also by pull bar 135 supportings.The two ends of each pull bar 134,135 are fixed on movable stereotype plate 132 ', the 133 ' and the 2nd side plate 138,138 '.Thus, movable stereotype plate 132,132 ', 133,133 ' can move back and forth along pull bar 134,135.In addition, the supporting member 144a on fixed head 142 and each linkage 143,144 is in stationary state.
The following describes the mold closing die sinking action of the manufacturing installation 100 of this example, with device specifies the linkage 143,144 that is in contraction state is upheld, the composite die B, the D that are fixed on the movable stereotype plate 132,133 is close to the composite die A, the C direction that are fixed on the slip stereotype plate 130, until carrying out mold closing.Meanwhile, move along slip stereotype plate 130 ' direction with the movable stereotype plate 132 ', 133 ' of linkage 143,144 action carrying out interlock, the composite die B, the D that are fixed on these stereotype plates are close to the composite die A, the C direction that are fixed on the slip stereotype plate 130 ', until carrying out mold closing.In addition, the 2nd side plate 138,138 ' that is fixed with these linkage 143,144 1 ends also moves with the expanding-contracting action interlock of linkage 143,144.The die sinking action is opposite with it.
The composite die B of the 1st metal pattern 110 is fixed on the movable stereotype plate 133 ', and the composite die D of the 2nd metal pattern 120 is fixed on the movable stereotype plate 133.Each movable stereotype plate 133,133 ' is configured in the position of 180 ° of subtends, and formation will be fixed with the form of respectively turning round stereotype plate 145,145 ' revolving body 146 clampings.Thus, composite die A and composite die B are the subtend shape, and composite die C and composite die D are the subtend shape, can carry out the mold closing die sinking.The other end of the linkage 144 with an end and the 2nd side plate 138 after fixing is fixed on the face of on the movable stereotype plate 133 and stationary plane opposition side composite die D.A pair of pull bar 134 supportings of movable stereotype plate 133 and substrate 148 usefulness.The two ends of each pull bar 134 are fixed on movable stereotype plate 133 ' and the 2nd side plate 138.Again, the supporting member 144a on substrate 148 and the linkage 144 is in stationary state.Thus, the composite die D, the B that are fixed on the movable stereotype plate 133,133 ' can be along pull bars 134, move back and forth to the direction with the direction quadrature of aforementioned gyroaxis.In addition, in this example, being with the dissimilarity of aforesaid example, in the 2nd metal pattern 120, is to carry out 120 die sinkings of the 2nd metal pattern under the formed body 140 that will obtain through secondary operations (pressurized, heated drying) remains on the state of composite die D.
In the manufacturing installation 100 of this example, composite die A and composite die D should have the holding device of the formed body of suction device etc. at least.Though also want the variety classes of root a tree name formed body, for example when making pulp mold formed body, the same with the example shown in Figure 15～Figure 21 A and Figure 21 B, all composite die A～D have holding device.
In the manufacturing installation 100 of this example, be to be undertaken to the handing-over of the fiber pad body of the 2nd metal pattern by revolution stereotype plate 145,145 ' revolution from the 1st metal pattern.Promptly, the revolving body 146 of fixing revolution stereotype plate 145 is from state shown in Figure 22, by 180 degree revolutions, makes composite die A that is fixed on the revolution stereotype plate 145 and the composite die D that is fixed on the movable stereotype plate 133 be the subtend shape.Then, make linkage 144 actions, the composite die D that is fixed on the movable stereotype plate 133 is close to composite die A direction, until carrying out mold closing (in addition, meanwhile, being fixed on composite die B and composite die C mold closing on the movable stereotype plate 133 ').And, under this mold closing state, carry out the handing-over of fiber pad body 139 to composite die D from composite die A.In addition, remain on turning round in the revolution action of stereotype plate 145 in the composite die D, discharge to next process with device specifies through the formed body after the secondary operations 140.
In addition, the mold closing die sinking action in this manufacturing installation of example 100 is identical with the action of the manufacturing installation of the example shown in Figure 21 A and Figure 21 B.
In the example of Figure 15～shown in Figure 22, for example, also can be with the plastics forming body as the shaping object.In this occasion, the molten resin parison is inserted in the die cavity in the 1st metal pattern 110, be blown into air to this parison, the formed body that will blow shaping.Again, in the 2nd metal pattern, the secondary operations of the coating of the content-filled and formed body inwall of enforcement in formed body etc.
Again, in the example of Figure 15～shown in Figure 20, be not that composite die B, D are fixed on the movable stereotype plate yet, be fixed on fixedly on the stereotype plate but change into, by make slip stereotype plate 130 relatively fixedly stereotype plate reciprocating motion relatively carrying out mold closing die sinkings move.
Again, be not limited to the occasion of above-mentioned example to the discharge of next process through the formed body 140 after the secondary operations, also can be in the 2nd metal pattern 120, after secondary operations, under the state of device specifies in the some composite die C, the D that formed body 140 are remained on the 2nd metal pattern 120, with composite die C, D die sinking, discharging sometime during from this die sinking to composite die C, D mold closing next time.
Again, in the present invention, also can after the secondary operations operation on the 2nd metal pattern, re-use more than one metal pattern, carry out once above manufacturing procedure, carry out the handing-over of the formed body of each inter process according to the method described above.
Again, in the example of Figure 15～shown in Figure 21, movable stereotype plate 132,133 (132 ', 133 ') is a monomer-type, but also can use the movable stereotype plate of one instead.
If adopt Figure 15～example shown in Figure 22, then can be provided under original state of keeping when being shaped, on the fiber pad body, implement the manufacture method and the manufacturing installation thereof of the formed body that secondary operations (pressurized, heated drying) obtains.On the formed body of making thus, can not apply mechanical deformation force, can not cause unnecessary deformation.Do not worry dislocation between incidental when using outside carrying device, fiber pad body and the metal pattern again.And, compare with the occasion of using outside carrying device, can reduce the die sinking amount, make equipment miniaturization, and can reduce process number, shorten the manufacturing cycle.
