With reference to Figure 11 (a), compression joint mechanism 230 possesses: base portion 231, erecting tools 232, support unit 233 and pressure contact portion 234.Base portion 231 is formed 2 hole 231a and each and every one tooth-strip part 231b.By penetrating axle 211 respectively in two hole 231a, thus base 231 is supported on axle 211 in the mode can slided in Y direction.In addition, as described above, tooth-strip part 231b is engaged with gear 205c, and by the rotation of gear 205c, base 231 is moved in the Y-axis direction.
Erecting tools 232 is arranged on base 231 by the axle 232a extended in the Z-axis direction, and only can rotate centered by axle 232a relative to base 231.Thus, make compression joint mechanism 230 when Y-axis pros move up as described later, easily make whole of the positive side of the Y-axis of pressure contact portion 234 to contact with film F.Support unit 233 is fixed on erecting tools 232, and pressure contact portion 234 is fixed on support unit 233.
With reference to Figure 11 (b), Figure 11 (c), pressure contact portion 234 has base portion 234a and projecting strip part 234b.Cross section during the observing in X-axis positive direction of projecting strip part 234b has the shape that the width on top is narrower compared with root.In the present embodiment, the cross section of projecting strip part 234b becomes triangle.The width of the Z-direction of base portion 234a is comparatively large compared with the width of the Z-direction of heater 224, and the width of the Z-direction of projecting strip part 234b is less compared with the width of the Z-direction of heater 224.In addition, base portion 234a is larger compared with the width of the X-direction of heater 224 with the width of the X-direction of projecting strip part 234b.
By pyroconductivity, the low and elastomeric material with heat resistance is formed base portion 234a, and projecting strip part 234b is made up of comparatively hard compared with forming the material of base portion 234a and the material with heat resistance.The pyroconductivity being preferably projecting strip part 234b is also lower.Base portion 234a and projecting strip part 234b is such as made up of resin material.Base portion 234a and the projecting strip part 234b of present embodiment comprise silicone polymer as main material, in addition, containing the various blenders headed by processing aids in silicone polymer.Projecting strip part 234b due to compared with base portion 234a to silicone polymer add silica series powdered filler addition more, therefore projecting strip part 234b is harder compared with base portion 234a.By utilizing mould, ester moulding is carried out to the resin material of base portion 234a and the resin material of projecting strip part 234b, thus projecting strip part 234b is integrated on base portion 234a.
As shown in Figure 11 (c), projecting strip part 234b be configured in base portion 234a compared with the central authorities of Z-direction to Z axis positive direction skew position.Therefore, in the face of the positive side of Y-axis of base portion 234a, the width of the downside of projecting strip part 234b is wider compared with the face of the upside of projecting strip part 234b.
Figure 12 (a) is for representing the stereogram of the structure of mechanism for stripping 240, and Figure 12 (b) is the side view of the structure represented when Y-axis positive direction observes mechanism for stripping 240.In addition, in Figure 12 (b), erecting tools 222, support unit 223 and heater 224 is illustrated in the lump via opening 241d.
With reference to Figure 12 (a), Figure 12 (b), mechanism for stripping 240 has base portion 241 and rubber 242.Base portion 241 is formed two hole 241a, a pair alar part 241b of resin manufacture, resin manufacture another to alar part 241c and opening 241d.Penetrate two hole 241a respectively by making axle 211 thus base portion 241 is supported on axle 211 in the mode that can slide in the Y-axis direction.A pair alar part 241b, 241c have the wing-like extended in Y-axis negative direction.By making compression joint mechanism 230 be transferred to Y-axis negative direction, thus alar part 241b, 241c are retrained the film F be transferred by two groups of rollers 105 and suppress the width in X-direction.
With reference to Figure 12 (b), opening 241d runs through base portion 241 in the Y-axis direction.Heater 224 becomes by the opening 241d of mechanism for stripping 240 state opened to Y-axis negative direction.Thus, when compression joint mechanism 230 moves to Y-axis positive direction, pressure contact portion 234 becomes and abuts with heater 224.
Figure 13 (a) ~ Figure 14 (b) is the figure be described the action of the film unit 30 when draining process.Figure 13 (a) ~ Figure 14 (b) be with parallel plane of Y-Z by the sectional view of film unit 30 cutting.Dotted line represents the film F near the Y-Z plane residing for two rollers 105 of the positive side of X-axis.
As shown in Figure 13 (a), under the state before sealing action, film F is clamped by two groups of rollers 105, and the end of film F is located in the position of the height of heater 224 periphery.In addition, the end of film F, is sealed when initial placement or when last time seals action.In this state, excreta etc. are accommodated in film F.
Excretas etc. are by collecting in film F, and afterwards, when sealing action starts, motor 103 (with reference to Fig. 8) is driven, and made by two groups of rollers film F downwards (Z axis negative direction) be transferred.Thus, the state shown in Figure 13 (b) is become.In addition, by such as after excretion operator or user to be inputted the mode of the instruction that excretion terminates by switch 41 and make sealing action start to perform.
Made after film F is transferred downwards by roller 105, motor 203 (with reference to Fig. 8) is driven, and compression joint mechanism 230 is transferred to Y-axis positive direction.Thus, the while of making the width of X-direction repressed by alar part 241b, 241c of mechanism for stripping 240, film F is made to be brought towards Y-axis positive direction.Further, when pressure contact portion is transferred to Y-axis positive direction, pressure contact portion 234 abuts with rubber 242 across film F, and resists the reaction force of spring 212 (with reference to Figure 10 (a)) and released to Y-axis positive direction by mechanism for stripping 240.And when making pressure contact portion 234 be transferred to Y-axis positive direction further, as shown in Figure 14 (a), pressure contact portion 234 and heater 224 are adjacent to across film F.
Now, as described above, when the pressure of pressure contact portion 234 pairs of heaters 224 reaches predetermined standard, torque limiter 207 becomes idle running.In the near future, the driving of motor 203 is stopped.In addition, as described above, even if the driving of motor 203 is stopped, but owing to making the reversion of gear 209 be prevented by worm gear 208 with engaging of gear 209, the pressure of pressure contact portion 234 pairs of heaters 224 can therefore also be maintained.
In this condition, heater 224 is driven, and film F is dissolved.Now, be formed in by the heat of the upper-side area of heater 224 next for accommodating going to the bottom of the film F of excreta etc., and by the heat of the underside area of heater 224, the top of the film F of having accommodated excreta etc. sealed.Further, the mid portion of heater 224, the heat of part that namely by projecting strip part 234b, film F is pressed make film F be cut off.Next, be described with reference to Figure 15 (a) ~ sealing action of Figure 16 (b) to film F.
When the sealing of film F and cut-out complete, compression joint mechanism 230 is to Y-axis negative direction rollback.Thus, pressure contact portion 234 is separated with heater 224 and rubber 242, and mechanism for stripping 240 is sent preset width by spring 212 to Y-axis negative direction.Now, the film F be close to by pressure contact portion 234 and heater 224 is only brought back to Y-axis minus side with preset width from the position of heater 224 by mechanism for stripping 240.Thus, even if when film F is close on heater 224, film F and heater 224 also can be made to peel off.In addition, now, owing to making film F be transferred slightly to top by roller 105, film F and heater 224 is therefore made to peel off more effectively.So, as shown in Figure 14 (b), fallen through the opening 40b (with reference to Fig. 3) of supporting mass 40 by the film F sealed.
When draining release when processing, then film unit 30 is back to the state shown in Figure 13 (a).In addition, the position fallen by film F after sealing arranges the chest etc. of the film F for reclaiming sealing, thus enables operator easily reclaim the film F of sealing.
Figure 15 (a) ~ Figure 16 (b) is the figure be described the sealing action of film F.Figure 15 (a) ~ Figure 16 (b) is the schematic diagram in the cross section of heater 224, pressure contact portion 234 and the film F represented when observing in X-axis positive direction.
As shown in Figure 15 (a), when pressure contact portion 234 is transferred to Y-axis positive direction, film F is crimped portion 234 and presses and send to Y-axis positive direction.And as shown in Figure 15 (b), pressure contact portion 234 and heater 224 are adjacent to via film F.Figure 15 (b) illustrates pressure contact portion 234 and heater 224 is adjacent to across film F but projecting strip part 234b not yet starts to carry out the welding of film F and the state of cut-out.
When starting to heat by heater 224 under the state shown in Figure 15 (b), the film F be between pressure contact portion 234 and heater 224 is melted a little by heating, as shown in Figure 15 (c), pressure contact portion 234 is transferred to Y-axis positive direction further.Thus, film F is made to be pressed on heater 224, by film F such welding shown in dotted line that base 234a and heater 224 clamp by the face of the base portion 234a of the upper side and lower side of projecting strip part 234b.Thus, form going to the bottom of film F by the face of the base portion 234a of the upside of projecting strip part 234b, by the face of the base portion 234a of the downside of projecting strip part 234b, the top of the film F of having accommodated excreta etc. is sealed.
In addition, larger compared with the pressure being made film F press to heater 224 by projecting strip part 234b makes film F press to heater 224 pressure with the face by base portion 234a.Further, because projecting strip part 234b is comparatively hard compared with base portion 234a, the situation being therefore same rigidity with projecting strip part 234b and base 234a is compared, and makes film F can become large to the pressure that heater presses by projecting strip part 234b.Thus, the summit of projecting strip part 234b is easier to enter film F, thus is easier to vertically keep out of the way in the film F of the Y-axis of projecting strip part 234b positive side place fusing.So, as shown in Figure 15 (c), because the summit of projecting strip part 234b has roughly touched heater 224, therefore film F is cut off by projecting strip part 234b.
In addition, when in Figure 15 (c), the heating of heater 224 is carried out, as shown in Figure 16 (a), pressure contact portion 234 continues to be sent to Y-axis positive direction.Thus, the summit due to only projecting strip part 234b becomes and is pressed the state of collapsing a little and contact with heater 224, therefore, it is possible to make film F be cut off effectively.
Then, as shown in Figure 16 (b), from the state that pressure contact portion 234 abuts with heater, pressure contact portion 234 returns to Y-axis negative direction thus is separated with heater 224.Thus, as shown in Figure 16 (b), the film F of upside is separated with the film F of downside.
(effect of embodiment)
According to the present embodiment, following effect can be obtained.
Owing to being provided with the projecting strip part 234b for cutting off film F on pressure contact portion 234, therefore do not need to arrange the parts being equivalent to the such heat conductivity of projecting strip part 234b in heater 224 side.Therefore, it is possible to improve the thermal efficiency of the heater 224 to film F heating, and number of components can be reduced.In addition, in the present embodiment, because pressure contact portion 234 is made up of the material that pyroconductivity is low, therefore the heat of heater 224 not easily runs off via pressure contact portion 234.According to this point, the thermal efficiency of heater 224 pairs of film F heating also can be improved.
In addition, because projecting strip part 234b is comparatively hard compared with base 234a, therefore the pressure that is crimped in film F of projecting strip part 234b is larger.Therefore, can effectively and effectively be made film F be cut off by projecting strip part 234b.
In addition, the cross section of projecting strip part 234b when X-axis positive direction is observed has the shape that the width on top is narrower compared with root.Thus, because the area being crimped on the projecting strip part 234b in film F diminishes, the pressure that therefore projecting strip part 234b crimps to film F improves.Therefore, film F can effectively and be effectively made to be cut off by projecting strip part 234b.
In addition, in the present embodiment, the cross section of projecting strip part 234b is triangle.Thus, because the area being crimped on the projecting strip part 234b in film F reduces significantly, be pressed against state in film F as become sharp keen cutlery, and film F can be cut off well.
In addition, base 234a and projecting strip part 234b is made up of resin material, and by carrying out ester moulding to each resin material, thus projecting strip part 234b is integrated on base 234a.Thereby, it is possible to cheap and be formed on base 234a by projecting strip part 234b well, and even if crimping action continues for a long time, projecting strip part 234b also can not depart from from base 234a.Thereby, it is possible to carry out welding and cut-out to film F well for a long time.
In addition, the resin material forming base 234a and projecting strip part 234b comprises silicone polymer as primary raw material.Thereby, it is possible to form base 234a and projecting strip part 234b more at an easy rate.In addition, because projecting strip part 234b is compared with base 234a, the addition of silica-based powder filled dose that adds in silicone polymer is more, so projecting strip part 234b is harder compared with base 234b.So, by regulate relative to silicone polymer containing thing, easily base 234a and projecting strip part 234b setting can be become required elasticity and hardness.
In addition, pressure contact portion 234 abuts with heater 224, after the movement of compression joint mechanism 230 is limited, even if continue drive motors 203, after the pressure putting on heater 224 at pressure contact portion 234 reaches predetermined standard, the torque limiter 207 be linked on gear 206 also will become idle running.Thus, the situation applying excessive load to motor 203 is prevented.
In addition, be stopped at the rear motor 203 of torque limiter 207 idle running, by the engagement of worm gear 208 and gear 209, the reversion of gear 209 prevented.Thereby, it is possible to while suppression power consumption, maintain the crimp force that compression joint mechanism 230 puts on heater 224.
In addition, after the sealing action implementing film F, owing to making film F successfully be stripped from heater 224 by mechanism for stripping 240, therefore, it is possible to prevent film F from remaining in situation on heater 224.
In addition, inventors of the present invention implement the measurement about the thermal efficiency practically, obtain result as shown in figure 17.In fig. 17, transverse axis represents the elapsed time, and the longitudinal axis represents the heter temperature be detected by thermocouple 225 (with reference to Figure 10 (b)).Solid line represents the passing of heter temperature when employing structure (hereinafter referred to as " embodiment ") identical with present embodiment.In an embodiment, opposed with heater elastomeric element is provided with projecting strip part.On the other hand, dotted line represents the passing of heter temperature when employing comparative example.In a comparative example, projecting strip part is not set on the elastomeric element relative with heater, and is provided with the thick aluminium parts of the 1mm with projecting strip part on the heaters.
In embodiment and comparative example, heater is mutually the same structure.In the measurement, under the state making heater and elastomeric element close contact not clamping film F, in 20 first second, heater is set as opening, and in ensuing 30 seconds, the opening of heater and closed condition were switched every 1.5 seconds.Afterwards, heater is set as opening.In a comparative example, arriving temperature is 69 degree, and climbing is 1 degree/second, and rate of descent is 0.07 degree/second.In an embodiment, reaching temperature is 152 degree, and climbing is 5 degree/second, and rate of descent is 1.5 degree/second.
Result according to Figure 17, in an embodiment, compared with comparative example, temperature rises very fast, arrives temperature higher.According to this situation, in an embodiment, compared with comparative example, the thermal efficiency of heater is higher.In addition, use embodiment, when in the mode same with this measurement heater being controlled thus perform the welding of film F and cut off action, well can implement welding and the cut-out of film F.According to this situation, the structure of above-mentioned embodiment has and is suitable for implementing the welding of film F and the structure of cut-out.
