<2-2. for spuing, process >
Next, spuing of the liquor 9 of above-mentioned liquor device for discharging fixed 1 processed and described.Fig. 4 is the flow chart of the handling process that represents to spue.
In this liquor device for discharging fixed 1, when spuing liquor 9, first, set the discharge-amount W(step S1 of liquor 9).For example, user's operating operation portion 12 of liquor device for discharging fixed 1 inputs arbitrarily the maximum pressure of gas and the standard ETAD expected time of arrival and departure of switch valve 56.If carry out this operation, just the maximum pressure based on input and standard ETAD expected time of arrival and departure are set the discharge-amount W of the liquor 9 that should spue in a disgorging motion.And the information of the discharge-amount W of setting is transfused in micro computer 40.
In addition, also can carry out by the method except described method the setting of discharge-amount W.For example, the user of liquor device for discharging fixed 1 also can operating operation portion 12 directly input the discharge-amount W of the liquor 9 that should spue in a disgorging motion.
Then, micro computer 40 is switched to the first state by switch valve 56 from the second state.That is, between the first pipe arrangement 51 and the second pipe arrangement 52, open switch valve 56(step S2).Like this, the gas that is filled in air accumulator 59 is supplied with to syringe 30 by the second pipe arrangement 52.Thereby, utilize the pressure of this gas to start from syringe 30 liquor 9 that spues.
Fig. 5 be to represent the switching of switch valve 56 and the figure changing at the pressure of the gas of the second pipe arrangement 52 interior generations due to this switching.The transverse axis of Fig. 5 represents the time.The longitudinal axis of Fig. 5 represents the state of switch valve 56 and the pressure of the gas in the second pipe arrangement 52.And what represent on the top of Fig. 5 is the situation of the liquor 9 completely measured in the interior filling of syringe 30 while starting to spue.What in the bottom of Fig. 5, represent is that the residual quantity of the liquor 9 in syringe 30 while starting to spue is than completely measuring few situation.
In addition, at this, the actual maximum residue limit that is filled in the liquor 9 in syringe 30 is called to " full amount ".Therefore, " full amount " also can be for being full of the state in the space in syringe 30 completely with liquor 9.
As shown in Figure 5, if switch valve 56 is switched to the first state from the second state, the pressure of the gas in the second pipe arrangement 52 increases gradually.And, in the situation on the top of Fig. 5, from switch valve 56 being switched to the first state, after standard time Tr1, reach maximum pressure Pa.On the other hand, in the situation of the bottom of Fig. 5, because the residual quantity of the liquor 9 in syringe 30 is fewer than full amount, so the space of this part is present in syringe 30.Therefore, long than standard time Tr1 to the rise time Tr2 that reaches maximum pressure Pa from switch valve 56 being switched to the first state.In the example of Fig. 5, between standard time Tr1 and rise time Tr2, produce the poor of Δ Tr time delay.
Like this, if the residual quantity of the liquor 9 in syringe 30 reduces, the rising of pressure P produces and postpones.Therefore, for be not subject to the liquor 9 in syringe 30 residual quantity impact and with the discharge-amount W the fixing liquor 9 that spues, need to extend the time (hereinafter referred to as " ETAD expected time of arrival and departure T ") that switch valve 56 is maintained to the first state according to the minimizing of the residual quantity of the liquor 9 in syringe 30.
Fig. 6 is illustrated in the discharge-amount W that sets in step S1 and the curve map of the relation between ETAD expected time of arrival and departure T.The relation that variation line 70 in Fig. 6 represents between discharge-amount W and the ETAD expected time of arrival and departure when the interior filling of syringe 30 is completely measured liquor 9 (hereinafter referred to as " standard ETAD expected time of arrival and departure Ts ").As by changing line 70 represents, by standard ETAD expected time of arrival and departure Ts along with the roughly linear function that the increase of discharge-amount W increases represents the relation between discharge-amount W and standard ETAD expected time of arrival and departure Ts.
And, the relation of ETAD expected time of arrival and departure T when variation line 71 expression discharge-amount W in Fig. 6 completely measure minimizing with the residual quantity ratio of the liquor 9 in syringe 30.As represented by variation line 71, at least to comprise the mode of the scope that the roughly linear function that increases along with discharge-amount W by ETAD expected time of arrival and departure T represents in the scope from minimum time T min to maximum time T max, control the relation between discharge-amount W and ETAD expected time of arrival and departure T.By the 3rd formula below the maximum pressure Pa substitution of syringe capacity V and gas, calculate minimum time T min, by the 4th formula below the maximum pressure Pa substitution of syringe capacity V and gas, calculate maximum time Tmax.And ETAD expected time of arrival and departure T is longer than standard ETAD expected time of arrival and departure Ts.In addition, as shown in the dotted line in Fig. 6, the ratio in variation line 71 is estimated to be curve-like by the little part of discharge-amount W of the scope that roughly linear function represents.
The 3rd formula: Tmin=[2+(0.15 * V)] * √ Pa
The 4th formula: Tmax=V * √ Pa
In addition, Tmin and Tmax result to control the intrinsic propesties of the control mode of the present utility model of discharge-amount by calculating the time expand of opening of valve.Even if for example, in the situation that the scope of being controlled by linear function is roughly only larger than Tmin and less than Tmax time range, control method of the present utility model also can be worked effectively in this scope.But, consider the actual purposes of the present utility model of utilizing, if cannot pass through the roughly ETAD expected time of arrival and departure of linear function by-pass valve control in a certain scope, can not become practical device.Therefore, be necessary Tmin and Tmax to limit.
In the present embodiment, for example, when syringe volume V=3cc, maximum pressure Pa=200kPa, in the scope from 26msec roughly to 80msec roughly, according to linear function roughly, control.The Tmin, the Tmax that according to the 3rd formula and the 4th formula, calculate are respectively 34msec, 42msec, and this meets the restriction for Tmin and Tmax.And, when syringe volume V=70cc, maximum pressure Pa=800kPa, in the scope from 200msec roughly to 2720msec roughly, according to linear function roughly, control.The Tmin, the Tmax that according to the 3rd formula and the 4th formula, calculate are respectively 354msec, 1979msec, and this meets the restriction for Tmin and Tmax.
Micro computer 40 determines ETAD expected time of arrival and departure T(step S3 according to the residual quantity of the discharge-amount W setting in step S1 and the liquor 9 in syringe 30).Thereby after switch valve 56 is switched to the first state, the first state only maintains the ETAD expected time of arrival and departure T that step S3 determines.Micro computer 40 is switched to the second state switch valve 56 from the first state through ETAD expected time of arrival and departure T.That is, between the first pipe arrangement 51 and the second pipe arrangement 52, close switch valve 56(step S4).
If switch valve 56 is switched to the second state, utilize the negative pressure being produced by injector 62 that the gas in the second pipe arrangement 52 is transported to the 3rd pipe arrangement 53.Thus, can promptly stop spuing of liquor 9.Like this, can prevent after the end that spues from the unnecessary liquor 9 of syringe 30 drippage.Consequently, can make the discharge-amount W of the more approaching setting of discharge-amount of the liquor 9 of syringe 30.
<2-3. for the decision of ETAD expected time of arrival and departure, process >
Fig. 7 for representing the processing of above-mentioned steps S3 in further detail, determine the flow chart of processing of the ETAD expected time of arrival and departure T of switch valve 56.Fig. 8 is the module map of calculation process that is shown schematically in the ETAD expected time of arrival and departure T of the interior decision switch valve 56 of micro computer 40.The decision of splitting time T referring to Fig. 7 and Fig. 8 is processed and is described.
As shown in Figure 8, micro computer 40 has storage part 43, discharge-amount instruction unit 44, action command portion 45, flow calculating section 46 and timer 47.Each function of the storage part 43 of present embodiment, discharge-amount instruction unit 44, action command portion 45, flow calculating section 46 and timer 47 is processed and is realized by the calculation in micro computer 40.
When determining ETAD expected time of arrival and departure T, first, determine standard ETAD expected time of arrival and departure Ts(step S31).Specifically, using the standard ETAD expected time of arrival and departure of the switch valve 56 of user's input when step S1 sets discharge-amount W as standard ETAD expected time of arrival and departure Ts.
But, the in the situation that user directly inputting discharge-amount W in step S1, also can determine standard ETAD expected time of arrival and departure Ts based on this discharge-amount W.At this moment, the discharge-amount W that the input signal of discharge-amount instruction unit 44 based on from operating portion 12 set to 45 indications of action command portion.In action command portion 45, set the data that are equivalent to the variation line 70 in Fig. 6 in advance.Action command portion 45 also can determine standard ETAD expected time of arrival and departure Ts by the discharge-amount W based on these data and indication.
Then, the rise time Tr2 of timer 47 gaging pressure P, pressure P is measured by the first pressure sensor 57.Specifically, the pressure P that the measuring-signal based on the first pressure sensor 57 is measured the gas in the second pipe arrangement 52 reaches the required rise time Tr2 of maximum pressure Pa.Thereby, obtain this rise time Tr2 with respect to Δ Tr(step S32 time delay of standard time Tr1).
As shown in Figure 5, time delay, Δ Tr changed according to the residual quantity of the liquor 9 in syringe 30.In the present embodiment, obtain this time delay Δ Tr and using the residual quantity reflection parameters R of as the reflection residual quantity of the liquor 9 in syringe 30.That is to say, when switch valve 56 is opened, obtain the rise time Tr2 being measured by timer 47 and using as residual quantity reflection parameters R with respect to Δ Tr time delay of standard time Tr1.
In the present embodiment, the first pressure sensor 57 and timer 47 play a role as the parameter acquiring section of obtaining residual quantity reflection parameters R.In other words, in the present embodiment, parameter acquiring section has the first pressure sensor 57 and timer 47.If Δ Tr reflects parameters R as residual quantity with time delay, do not need directly to measure the residual quantity of the liquor 9 in syringe 30.
Then, flow calculating section 46 is calculated the flow Q(step S33 of the liquor 9 spuing from syringe 30).Store the diameter d of the inner peripheral surface of spray nozzle part 32, the inner space of spray nozzle part 32 is spuing in storage part 43 length L in direction and the viscosity, mu of liquor 9.In step S33, flow calculating section 46 reads diameter d, length L and viscosity, mu from storage part 43.And flow calculating section 46 is obtained the pressure P of the gas of the second pipe arrangement 52 from the first pressure sensor 57.Preferred maximum pressure Pa after rising using the pressure P of obtaining at this.Thereby flow calculating section 46 is calculated the flow Q(step S33 of liquor 9 by the second formula below the pressure P substitution of the viscosity, mu of the length L in the direction that spues, liquor 9 and the gas of the second pipe arrangement 53 by the inner space of the diameter d of the inner peripheral surface of spray nozzle part 32, spray nozzle part 32).In addition, π is pi.
The second formula: Q=(P * π * d
4)/(128 * μ * L)
Thus, infer the flow Q of the liquor 9 spuing from syringe 30.Like this, can just obtain without actual measurement the flow Q of the liquor 9 that spues from syringe 30.The flow Q calculating to 45 indications of action command portion.That is, in the present embodiment, the flow instruction unit of the flow Q of the liquor 9 that flow calculating section 46 spues from syringe 30 as indication plays a role.In other words, flow calculating section 46 is also also used as the fluid instruction unit of indicating the flow Q being calculated by flow calculating section 46.
Fig. 9 is for representing the figure of the more detailed shape of syringe 30.As shown in Figure 9, storage portion 31 has storage main part 311, the first reducing diameter part 312 and inner side connecting portion 313.On the other hand, spray nozzle part 32 has outside connecting portion 321, the second reducing diameter part 322 and nozzle body portion 323.By outside connecting portion 321 being assemblied in to the outer peripheral face of inner side connecting portion 313, carry out being connected of storage portion 31 and spray nozzle part 32.
In the situation that syringe 30 has such shape, above-mentioned diameter d for example also can be regarded as the diameter d of the inner peripheral surface of nozzle body portion 323.And, the length L of the inner space that above-mentioned length L for example also can be regarded as nozzle body portion 323 in the direction that spues.
Next, action command portion 45 using as residual quantity reflection parameters R time delay Δ Tr and the indicated flow Q substitution of flow calculating section 46 below the first formula.Thus, calculate out time expand Td(step S34).In addition, C is coefficient.
The first formula: Td=C * Δ Tr/Q
That is, open time expand Td and depend on the first formula.
That at this, calculates in addition, opens the ETAD expected time of arrival and departure of time expand Td when the some place that is zero by the linear function that is included in the variation line 71 in Fig. 6 at discharge-amount W extrapolating.As shown in Figure 6, open time expand Td on the occasion of.And, according to the first formula, open time expand Td along with Δ Tr increase time delay and increase, open time expand Td along with the residual quantity minimizing of liquor 9 and increase.And, open time expand Td along with time delay Δ Tr reduce and reduce, open time expand Td along with being that the residual quantity of liquor 9 increases and reduces.
Figure 10 is the curve map that represents the flow Q of liquor 9 and open the relation between time expand Td.The transverse axis of Figure 10 represents flow Q.The longitudinal axis of Figure 10 represents out time expand Td.If suppose that time delay Δ Tr is constant, as shown in figure 10, opens the subtraction function that time expand Td is relative discharge Q.That is, open time expand Td along with the residual quantity Q minimizing of liquor 9 and increase and open time expand Td along with the flow Q increase of liquor 9 and reduce.And, as shown in figure 10, open the increase of flow Q of relative liquor 9 of time expand Td and the size that reduces along with the flow Q of liquor 9 increases and diminishes.
The flow Q that Figure 11 is the liquor 9 that actual measurement spues from a certain syringe 30 respectively and the correction factor relevant to opening time expand Td also carry out the curve map of pictorialization.Result with reference to Figure 11 can find out, correction factor increases and reduces with the flow Q of liquor 9.And, the increase of the flow Q of the relative liquor 9 of correction factor and the size that reduces is roughly fixing.Even if condition determination changes, the actual measured value of Figure 11 changes, and correction factor also can not be subject to the impact of condition determination and have identical tendency with respect to the inclination of flow Q itself.
In the present embodiment, with reference to the result of such Figure 11, set above-mentioned the first formula.That is, open time expand Td and depend on the first formula representing by Td=C * Δ Tr/Q.Thus, can calculate out rightly time expand Td according to the flow Q of liquor 9.
Then, action command portion 45 is added on by opening time expand Td the ETAD expected time of arrival and departure T(step S35 that standard ETAD expected time of arrival and departure Ts calculates switch valve 56).By above calculation, process, can extend according to the residual quantity of the liquor 9 in syringe 30 the ETAD expected time of arrival and departure T of switch valve 56.Thus, can not be subject to liquor 9 residual quantity impact and from the syringe 30 roughly quantitative liquor 9 that spues.And the flow of the liquor 9 based on spuing from syringe 30 is calculated out time expand Td.Thus, can reduce mensuration and the experiment of carrying out in advance in order to determine out time expand Td.
