The specific embodiment
In specification of the present invention, the mounting table that is positioned at the injection phase is called as the injection mounting table, and the finishing die that remains on this injection mounting table is called as the injection molding mould.
Foam forming device of the present invention be have can around the rotation of the rotating shaft of level and from rotating shaft to radiate planar outstanding a plurality of mounting tables and to make the rotating mechanism of a plurality of mounting tables rotations, promptly so-called vertical revolving building mortion.Thereby, can in less space, produce, the production quantity of comparing unit are with the conveyer belt mode improves a lot.
In the foam forming device of the present invention, at first when a mounting table is positioned at the injection phase, in the injection molding mould that remains in this injection mounting table, inject Foamex from inlet.And rotating mechanism have till next mounting table arrives the injection phase during in angle arbitrarily with the injection molding mould with injecting the shut-down mechanism that mounting table temporarily stops.Thereby in the injection molding mould after temporarily stopping, according to its angle Foamex is flowed, so can by adjust this arbitrarily angle Foamex is flowed to any direction, and then can prevent from finished product, to produce defectives such as air trap, misrun.
A plurality of mounting tables constitute in the following manner, fix a plurality of mounting tables on a rotating shaft, and the rotation by rotating shaft is rotated its phase mutually synchronization.Thereby owing to can set the angle of the mounting table of the desired location that is positioned at liner or the demoulding position of mechanograph etc. arbitrarily, thus can be according to the angle of operator's change mounting tables such as height or highly, for the operator creates the good working environment.
Though also can under the state of mounting table rotation, inject in addition or carry out the demoulding, preferably under the rotation halted state of mounting table and finishing die, carry out the configuration of the demoulding, liner and the injection of Foamex.That is, preferably shut-down mechanism can be respectively stops the rotation of mounting table in the injection phase of the allocation position of demoulding position, liner and Foamex.
As this shut-down mechanism, can adopt the rotary encoder that can detect the anglec of rotation or resolver etc. and can control the servo-drive system of position of rotation, the motor etc. that is subjected to pulse controlled stepper motor and can carries out the band brake of sequential control according to the external input signal of non-contact switch etc. with stopping by programmable positioning unit.Here, stop precision or carry out complexity control, preferably use servo-drive system in order to improve.
Number to mounting table has no particular limits, and is generally 2～8, but considers that angle (maximum about 60 °) or production efficiency that mounting table can tilt are preferably 4～6.In addition, preferably adopt servomotor to control rotation, can also constitute with the driving transfer part of decelerator or synchronous band etc. as rotating mechanism.Perhaps, also can carry out rotation intermittently by cam mechanism etc.
Rotating mechanism preferably has and can set the input mechanism at any angle that temporarily stops by platform to each mounting table respectively.If so just can set the angle that temporarily stops respectively according to the difference of the precision of each finishing die.In addition, also can be suitable for even mix the finishing die that is loaded with different types of mechanograph that is shaped.
In addition, rotating mechanism preferably has and can pursue the input mechanism of platform setting with the arbitrarily angled time that temporarily stops to each mounting table respectively.That is,, just can adjust the time that Foamex flows, and can carry out finer control, thereby can prevent from mechanograph, to produce defectives such as air trap, misrun more by adjusting the time that temporarily stops.In addition, just become easier, also become easy even mix the finishing die correspondence that is loaded with different types of mechanograph that is shaped with the corresponding adjustment of difference of the precision of each finishing die.
Can adopt keyboard, touch panel, toggle switch, by-pass cock (volume switch) etc. can import the mechanism of the parameter that is used to control rotating mechanism arbitrarily by manually-operated as this input mechanism.
And then rotating mechanism also can be when temporarily stopping at arbitrarily angle, makes to inject mounting table and carry out trickle swing or vibration on this position.By doing like this, can further improve the flowability of Foamex sometimes.
In addition, foam forming device of the present invention preferably also has band perpendicular to rotating shaft and be fixed in rotating shaft and with the pressing plate of rotating shaft rotation synchronously with by pushing press surface when arbitrarily angled and via the fixing retainer of pushing that injects mounting table of pressing plate temporarily stopping at.If so just can prevent by decelerator and synchronously band wait the back clearance (backlash) of driving transfer part of rotating mechanism or band lax caused the becoming flexible of stop position, thereby can make Foamex stably mobile.
And then, pushing circle is delineated out on the surface of press surface on press surface track owing to push retainer, so form press surface at least in the form of a ring, also can push reliably even at random change the angle that temporarily stops thus along this track.As long as thereby the shape with press surface pressing plate does not at least in the form of a ring just have special restriction.In addition, as long as pressing plate is fixedly installed in rotating shaft and rotates synchronously with rotating shaft, can engage with at least one side in rotating shaft and the mounting table.If consider the stress that is produced when retainer is pushed press surface pushing, preferably be engaged in the mounting table that can increase bonding area.
In addition, in another foam forming device of the present invention, rotating mechanism has gear, this gear from inject in the injection phase Foamex begin till next mounting table arrives the injection phase during, can at random adjust the rotary speed of injecting mounting table.As increase the rotary speed of injecting mounting table, and then the variation of the flow direction of the Foamex in the injection molding mould is accelerated, and flow reduces.As reducing rotary speed, then the variation of flow direction is slowed down in addition, and flow increases.Thereby, just can adjust flowing of Foamex by adjusting rotary speed, and can prevent from mechanograph, to occur defectives such as air trap or misrun.
As this gear, the converter etc. that can adopt servo-drive system and can change frequency by external signal with the servo amplifier that is used for realization speed control.Situation for carrying out complicated speed control preferably adopts servo-drive system.
In this foam forming device, rotating mechanism preferably has the input mechanism of each mounting table being set the rotary speed of injecting mounting table by platform arbitrarily.That is, adjust rotary speed, just can adjust flowing of Foamex thus according to the precision difference of each finishing die.In addition, though mix be loaded with shaping not the finishing die of mechanograph of the same race also can be suitable for.
Embodiment
By the following examples the present invention is specifically described.
The perspective view of the foam forming device of the expression first embodiment of the present invention among Fig. 1.A pair of foot 2, the two ends rotation that bearing 20 was vertically set up and had at the top respectively to this foam forming device by pedestal 1, from pedestal remains in rotating shaft 21 that pair of bearings 20 and along continuous straight runs extend freely and constitutes to be mutually 4 tabular mounting table 3a～3d that the mode of 90 ° of angles is fixed with rotating shaft 21.Linking servomotor 4 on an end of rotating shaft 21, rotating shaft 21 and mounting table 3a～3d are rotated along the direction of arrow among Fig. 1 by servomotor 4 and stop to drive.
On 4 mounting table 3a～3d, maintain finishing die 5a～5d respectively, rotate, stop with mounting table 3a～3d.Finishing die 5a～5d by the 1st mould 50 with the 1st mould mutually the 2nd mould 51 of matched moulds constitute, by under the interior state that core, stay (stay) and epidermis be housed, carrying out the headrest that foaming and molding comes the forming machine motor-car.
Servomotor 4 is controlled by control device shown in Figure 2.This control device is made of the CPU42 that is connected with touch panel 41, the positioning unit 40 that is connected with CPU42 and then the servo amplifier 44 that is connected with positioning unit 40 and the RAM45 that is connected to CPU42.Wherein, servomotor 4 adopts " HC-SF102B " (Mitsubishi Electric's system, 1KW), positioning unit 40 adopts " AISD75M3 " (Mitsubishi Electric's system, be assembled with order tooth bar (sequencerack)), servo amplifier 44 adopts " MR-J2S-100B " (Mitsubishi Electric's system), and touch panel 41 adopts " Pro-face GP477R-EG11 " (デ ジ Le system).
Then based on be stored among the RAM45 table and from the input of touch panel 41, positioning unit 40 can make servomotor 4 stop with rotation amount arbitrarily, and, can be in rotary course rotary speed be changed in position arbitrarily.
Set in the picture in the mounting table of touch panel 41, as shown in Figure 3, input by finishing die 5a～5d respectively formed thereby kind and have or not the injection Foamex, and set corresponding hardening time.If be injected to " nothing " of Foamex then means the unsaturated production that does not form in the finishing die of correspondence.
In addition in kind is set picture, be stored in table among the RAM45 and be read out and show as shown in Figure 4.Just demonstrate each kind injection length, have or not temporarily stop, the angle of inclination of the angle of inclination of the relation of the anglec of rotation and speed, the mounting table 3a when temporarily stopping～3d and the mounting table 3a on operating position～3d, with the corresponding rotary speed in angle of inclination etc.Thereby the operator is chosen in mounting table and sets each kind that sets in the picture and import, particularly under the situation that the condition that will change is arranged with its input.
The situation of production kind 3 in finishing die 5a～5d whole at first, is described.Under the situation of kind 3, the angle of inclination of setting for as shown in Figure 4 with 30 ° stops 2 seconds.Thereby servomotor 4 is controlled so as to as shown in Figure 5 and is rotated repeatedly and stops.Just, the operating period rotation stops to carry out the demoulding the operator, pack into etc., operate not shown switch by the operator foaming urethane resin is injected, begin rotation afterwards, on the temporary transient stop position that has rotated predetermined angular (30 °), rotate and temporarily stopped.Stopping the stipulated time after (2 seconds) then, automatically beginning rotation once more, amounting to from previous halted state when having rotated 90 °, rotation is automatically stopped, and then continues to stop till operator's console switch.
At Fig. 1 and position A shown in Figure 6, injecting its surface of mounting table 3a becomes horizontal plane and is in halted state.The operator opens along the direction of arrow of Fig. 1 and remains in the 2nd mould 51 that injects mounting table 3a.After mechanograph was carried out the demoulding, the core of packing into, stay and epidermis carried out interim matched moulds then.Afterwards, the operator operates not shown switch.Like this, inlet 6 descends, and inserts the foaming urethane resin that ormal weight is injected in the back in the injection molding mould 5a, rises afterwards.If inlet 6 withdraws from from finishing die 5, then the elasticity by epidermis make injection molding mould 5a not shown inlet by obturation, fully carry out matched moulds again and so constitute.
Like this, servomotor 4 is driven and rotating shaft 21 is rotated with the speed of 12rpm, and 4 mounting table 3a～3d are driven in rotation simultaneously.At this moment, servomotor 4 automatically temporarily stops after having rotated 30 °, and this temporary transient halted state continues 2 seconds.Under this temporary transient halted state, injecting mounting table 3a as shown in Figure 7 stops under the state with respect to 30 ° of horizontal line inclinations, in remaining in the injection molding mould 5a that injects mounting table 3a, liquid foaming urethane resin under the effect of gravity towards the 1st mould 50 side flow.By flowing like this, the situation that produces defectives such as air trap or misrun in mechanograph must be to prevent.
After above-mentioned temporary transient halted state continued 2 seconds, servomotor 4 began rotation once more, automatically stops fully after being further rotated 60 °.The mounting table 3d that is in the D position under this state just becomes level, by the operator mounting finishing die 5d is thereon carried out operation same as described above.
Then, servomotor carries out with above-mentioned same rotation repeatedly on one side, stops, stop after total has been rotated 360 ° in about 480 seconds on one side, thus, inject mounting table 3a through a week back home position A, finish foaming, the curing of foaming urethane resin during this period, so the headrest after finishing foaming and molding is carried out the demoulding in the A position.
Thereby foam forming device according to present embodiment, inject mounting table 3a and under 30 ° the state of having tilted with respect to horizontal line, temporarily stop 2 seconds, Ye Tai foaming urethane resin is in the effect current downflow of gravity thus, spread all over validly in the cavity by flowing, so just can prevent from mechanograph, to produce defectives such as air trap or misrun.
In addition, because angle that injection mounting table 3a temporarily stops and time can be set picture by kind and set arbitrarily, so by setting rightly according to the shape of mechanograph, the precision of finishing die etc., although then the difference of the kind of mechanograph or finishing die etc. can both prevent to produce defectives such as air trap or misrun reliably in mechanograph.
Fig. 8 expresses the foam forming device of present embodiment.In the foam forming device of present embodiment, on the two sides of 4 mounting table 3a～3d, engage respectively and be fixed with circular pressing plate 7, in a pair of foot 2, maintain cylinder assembly 8 respectively, be mounted on the surface (press surface) that the pressing component 80 (pushing retainer) of front end of the piston rod of cylinder assembly 8 can be pushed pressing plate 7.Other structure is identical with embodiment 1.Front end at pressing component engages flexible body, the impact when pushing with buffering.
Promptly in the foam forming device of present embodiment, when injection mounting table 3a had temporarily stopped 2 seconds with the state with respect to 30 ° of horizontal line inclinations, a pair of cylinder assembly 8 was driven, and the pressing component 80 of cylinder assembly 8 is pushed the surface of pressing plate 7 respectively.Thus mounting table 3a～3d with regard to become prevented by the hold mode of a pair of pressing component 80 clampings loosening, institute so that flowing of the foaming urethane resin in the injection molding mould 5a stablize.In addition, the part that pressing component 80 is pushed on the surface of pressing plate 7 is just delineated out circular track on the surface of pressing plate 7, exist the surface of pressing component 80 reliably along this track.Even also can push pressing plate 7 reliably thereby change takes place the angle that temporarily stops.
The formation of the foam forming device of present embodiment is identical with embodiment 1 except the control content difference of servomotor 4.Present embodiment relates to the situation of the kind 9 in the shop drawings 4, and servomotor 4 does not temporarily stop but making speed variable and controlled like that by time diagram shown in Figure 9.
Promptly, after the foaming urethane resin has been injected in the A position of halted state, begin rotation with big rotary speed (15rpm), tilted 20 ° the time with respect to horizontal line in the angle of injecting mounting table 3a, rotary speed is decelerated and becomes little rotary speed (5rpm), becomes big rotary speed (15rpm) in the angle inclination moment at 45 of injecting mounting table 3a.Thereby the foaming urethane resin just successfully along inclined direction flows in injection molding mould 5a.
Afterwards, rotary speed strengthens once more, and the moment rotation that is in B position (90 °) at injection mounting table 3a is stopped.Do like this and also can play the action effect identical with embodiment 1.Compare with embodiment 1 in addition, owing to can save deceleration or the acceleration time that is used to stop, so just produce effect wanting to shorten under the situation of rotating traveling time.
Embodiment 4
The formation of the foam forming device of present embodiment is identical with embodiment 1 except the control content difference of servomotor 4.Present embodiment relates to the situation of embodiment 1 and embodiment 3 having been carried out combination, and servomotor is controlled like that by time diagram shown in Figure 10.
Promptly, in the A position of halted state after finishing die 5a has injected the foaming urethane resin, begin rotation with big rotary speed (15rpm), tilted 20 ° the time with respect to horizontal line in the angle of injecting mounting table 3a, rotary speed is decelerated and becomes little rotary speed (5rpm), becomes big rotary speed (15rpm) in the angle inclination moment at 45 of injecting mounting table 3a.Thereby the foaming urethane resin just successfully along inclined direction flows in injection molding mould 5a.
Rotary speed strengthens once more afterwards, stops when angle that injecting mounting table 3a becomes 80 ° with respect to horizontal line, and mounting table 3d is positioned at from the A position by 10 ° of belows.Thus the operator with mechanograph from the demoulding of finishing die 5d with pack into and just become easy.
Pack into finish after, operator's console switch is rotated driving, becomes under the state that is positioned at horizontal level at mounting table 3d to stop once more.The urethane resin that foams afterwards is injected into shaping mould 5d, is rotated driving afterwards similarly to Example 1.
Become level at mounting table 3c in addition, after in finishing die 5c, having injected the foaming urethane resin, rotary speed with big (15rpm) begins rotation, having tilted with respect to horizontal line in the angle of mounting table 3c, rotary speed is decelerated 20 ° the time, slows down in the case and divides two stages to carry out.Mounting table 3b is driven in rotation similarly to Example 1 then, has rotated a circulation that is shaped under 360 ° the state at mounting table 3b and has just finished.
Thereby,, just can temporarily stop or slowing down, and can at random set deceleration conditions at each finishing die 5a～5d switching at random under heeling condition according to the foam forming device of present embodiment.Thereby exist at finishing die under the situation of mechanograph of error or shaping xenogenesis, also can at random adjust flowing of liquid foaming urethane resin according to each finishing die.
Promptly, according to foam forming device of the present invention, it is self-evident that the original function basis that can produce efficiently in narrow space is achieved this point, and can in each finishing die, at random adjust flowing of Foamex in the finishing die and need not to increase newly and be used for mechanism that finishing die is tilted, so just can prevent defectives such as generation air trap or misrun in mechanograph at an easy rate.
