Fig. 1 show electronic type liquid filling device of the present utility model structure and with the annexation of material cylinder 21, vacuum chamber 18 and release chamber 19.Electronic type liquid filling device of the present utility model comprises evacuation passageway and discharge channel.As shown in Figure 1, evacuation passageway comprises muffler 14, hollow valve stem 5, contiguous block 2 and the swing pipe 24 that is interconnected successively.Discharge channel is the gas channel 55 that is arranged in the valve seat 8.
One end of the upper end of valve rod 5 and swing pipe 24 is interconnected by contiguous block 2.In specific embodiment shown in Figure 1, the end of the upper end of valve rod 5 by the connecting bore below being positioned at contiguous block 2 inserts contiguous block 2 and links to each other with contiguous block 2, one end of swing pipe 24 (for example left end among Fig. 1) is from being positioned at the side of contiguous block 2, for example the other end of the connecting bore on the right side inserts in the contiguous block 2, and the other end of swing pipe 24 (for example right-hand member among Fig. 1) links to each other with vacuum chamber 18 by the independent vacuum valve 26 that is provided with.Reliably be connected between the upper end that this contiguous block 2 is used for when valve rod 5 up-and-down movements guaranteeing valve rod 5 and the end of swing pipe 24, preferably by elastomeric material, for example rubber etc. is made.Certainly, at swing pipe 24 is the flexible pipe of elastically deformable, for example when flexible metal conduit, bellows etc., also can omit contiguous block 2, and the connection structure that the hollow space that is formed for making valve rod 5 in the upper end of valve rod 5 is connected with an end of swing pipe 24, in the case, evacuation passageway then comprises muffler 14, hollow valve stem 5 and the swing pipe 24 that is interconnected successively.When liquid container 15 is carried out vacuum pumping, one end of evacuation passageway is connected with liquid container 15, the other end of evacuation passageway links to each other with vacuum chamber 18 via vacuum valve 26, and the gas from liquid container 15 in the liquid container 15 flows into vacuum chamber 18 via evacuation passageway and vacuum valve 26 successively.
Discharge channel is configured such that an end of discharge channel when unloading press operation is connected with liquid container 15, and the other end is connected to release chamber 19 via pressure-relief valve 17.As shown in Figure 1, the gas channel 55 as discharge channel is arranged in the valve seat 8 that joins material cylinder 21 bottoms to.Valve seat 8 has and is used for liquid material 20 is filled to liquid outlet 81 in the liquid container 15.When vacuumizing, inflating back pressure and unloading press operation, the inner peripheral surface liquid leakproof fit of the outer peripheral face of valve rod 5 lower ends and liquid outlet 81, to liquid container 15 filling liquid materials 20 time, the outer peripheral face of valve rod 5 lower ends and the inner peripheral surface each interval of liquid outlet 81 form the liquid ebb interval.The mode that valve seat 8 is connected with the bottom opening 52 of material cylinder 21 with liquid outlet 81 joins the bottom of material cylinder 21 to.(all around) further is provided with sealing arrangement 54 with the joint of material cylinder 21 bottoms around the liquid outlet 81 of valve seat 8, reveals from joint to prevent liquid material 20.In addition, also can be with the bottom formation one of valve seat 8 with material cylinder 21, this moment, liquid outlet 81 correspondingly became an opening with bottom opening 52.Muffler 14 stretches out downwards from liquid outlet 81, can go deep into the liquid container 15 from liquid container 15 oral areas, and the periphery wall of muffler 14 radially (laterally) size less than radially (laterally) size of the internal face of liquid outlet 81.One end of gas channel 55 is connected with liquid outlet 81, and be positioned at liquid outlet 81 can with the leakproof fit position of valve rod 5 lower end liquid under, the other end of gas channel 55 is connected to release chamber 19 by the independent pressure-relief valve 17 that is provided with.Therefore discharge channel is near that end of liquid container 15, and promptly an end of gas channel 55 is positioned at liquid container 15 oral areas top, and it must be positioned on the liquid level of liquid container 15 when filling liquid finished.
From top explanation as can be seen, compare with the prior art that evacuation passageway and discharge channel overlap each other, the difference of electronic type liquid filling device of the present utility model is, evacuation passageway and discharge channel are two gas channels that are provided with independently of one another, and that end of the close liquid container 15 of discharge channel, an end that is gas channel 55 is positioned on the liquid level of liquid container 15 when filling liquid finishes, and that end of the close liquid container 15 of evacuation passageway is under liquid level.Therefore when can finished, liquid material can not enter in the discharge channel, made the inadequate defective of release because of liquid material stops up discharge channel with regard to not occurring in the prior art when release yet.In addition, the liquid material that remains in the evacuation passageway can be sucked out by vacuum pumping before next can, avoided influencing next filling liquid.
Electronic type liquid filling device of the present utility model such as further comprises at pressure passageway.As shown in Figure 1, the muffler 14, hollow valve stem 5, contiguous block 2 and the swing pipe 24 that wait pressure passageway to comprise to be interconnected successively promptly wait pressure passageway and the evacuation passageway can a shared passage.Both differences are, wait the other end of pressure passageway to insert back pressure cavity 22 through fast filling valve 28 that is provided with independently of one another and flood irrigation valve 27, and the other end of evacuation passageway insert vacuum chamber 18 through vacuum valve 26.The shared configuration of this pressure passageway such as grade and evacuation passageway can be simplified the structure of electronic type liquid filling device.Yet, also isobaric channels configuration can be become descend the one end to link to each other with liquid container 15 in working order and its other end through fast filling valve 28 that is provided with independently of one another and flood irrigation valve 27 access back pressure cavity 22, and evacuation passageway gas channel independent of each other; Perhaps make and wait only partial common of pressure passageway and evacuation passageway, for example, can be only shared Deng pressure passageway and evacuation passageway at muffler 14 that links to each other successively and hollow valve stem 5 places, and separated from one another in other parts, for example can be by adopting two swing pipes 24 independent of each other linking to each other with contiguous block 2 from the side of contiguous block 2 part of formation pressure passageway such as grade and evacuation passageway respectively.
Fast effective air communication of irritating valve 28 is crossed sectional area and is crossed sectional area greater than effective air communication of flood irrigation valve 27.Wherein, " effectively air communication cross sectional area " refers to the effective cross sectional area that the gas channel of air valve can make air communication cross, and its numerical value depends primarily on the minimum sectional area of gas channel in the air valve and the apparent order and condition of gas channel.Under the certain situation of the draught head at the gas channel two ends of air valve, effectively to cross sectional area more little for air communication, and the gas volume that flows through air valve in the unit time is more little, and effectively to cross sectional area big more for air communication, and the gas volume that flows through air valve in the unit time is big more.Generally speaking, under the identical situation of the apparent order and condition of gas channel, the minimum sectional area of gas channel is more little, and it is more little that effective air communication is crossed sectional area, and the minimum sectional area of gas channel is big more, and it is big more that effective air communication is crossed sectional area.Under the identical situation of minimum sectional area, the surface of gas channel is smooth more, and it is big more that then effective air communication is crossed sectional area, otherwise then more little.During filling liquid, form the liquid leakproof fit between the oral area of liquid container 15 and the liquid outlet 81, muffler 14 stretches in the liquid container 15, fast filling valve 28 or flood irrigation valve 27 are unlocked, make liquid container 15 and back pressure cavity 21 communicate with each other, thereby the pressure in liquid container 15 and the back pressure cavity 21 is equated, and it is identical with the difference of pressure at the gas channel two ends of flood irrigation valve 27 open period flood irrigation valves 27 promptly to irritate the difference of pressure at gas channel two ends of valve 28 soon at fast filling valve 28 open periods.In the case, because fast effective air communication of irritating valve 28 is crossed sectional area and crossed sectional area greater than effective air communication of flood irrigation valve 27, so gas flows back to the air-flow velocity of the speed of back pressure cavity 21 greater than flood irrigation valve 27 open periods at fast valve 28 open periods of irritating from liquid container 15.Correspondingly, liquid material 20 in fast speed of irritating valve 28 open period influent containers 15 also just greater than the flow velocity of flood irrigation valve 27 open periods.
Further, fast irritate that valve 28 and flood irrigation valve 27 such as are configured to control independently of one another at pressure passageway and back pressure cavity 22 is interconnected, that is to say, fast irritate in valve 28 and the flood irrigation valve 27 any one unlatching pressure passageway and back pressure cavity 22 are interconnected, and the unlatching of irritating valve 28 and flood irrigation valve 27 is soon carried out independently of one another.Valve 28 is irritated in opening and closing soon, opening and closing flood irrigation valve 27 successively carries out successively.Promptly during filling liquid, fast filling valve 28 is opened, flood irrigation valve 27 is in closed condition at this moment, and the gases in the liquid container 15 can return back pressure cavity 22 by waiting pressure passageway and fast filling valve 28.Close fast filling valve 28 then and open flood irrigation valve 27, the gas in the liquid container 15 can return back pressure cavity 22 by waiting pressure passageway and flood irrigation valve 27.After treating that filling liquid is finished, close flood irrigation valve 27.
This shows, compare with the electronic type filling apparatus of the prior art that only is provided with a filling valve, another difference of the present utility model is, cross two different filling valves of sectional area Deng pressure passageway by effective air communication---irritate valve 28 soon and link to each other with back pressure cavity 22 with flood irrigation valve 27, fast valve 28 and the flood irrigation valve 27 of irritating can be controlled independently and wait pressure passageway and back pressure cavity 22 to be interconnected, and valve 28 is irritated in opening and closing soon during filling liquid, opening and closing flood irrigation valve 27 priorities are carried out successively.Electronic type liquid filling device of the present utility model at first makes fast filling valve 28 unlatchings and carries out quick can, make the liquid level in the liquid container 15 to reach a certain height fast, flood irrigation valve 27 opened and carried out can at a slow speed, make liquid material 20 be difficult for sneaking into bubble than low velocity influent container 15.In addition, fast the bubble of sneaking into during can eliminated during the can at a slow speed gradually, thereby further suppresses or eliminated the influence of quick can to the liquid level precision.Like this, electronic type liquid filling device of the present utility model can be taken into account filling speed and filling accuracy better, can realize accurate can with fast speeds.
Electronic type liquid filling device of the present utility model further comprises the valve rod actuation gear.This valve rod actuation gear can make valve rod 5 move downward to make the leakproof fit off position of liquid between the inner peripheral surface of the outer peripheral face of valve rod 5 lower ends and liquid outlet 81, and valve rod 5 is moved upward to make the open position that forms the liquid ebb interval between the inner peripheral surface of the outer peripheral face of valve rod 5 lower ends and liquid outlet 81.This valve rod actuation gear further comprises the valve rod actuating mechanism that can promote valve rod 5 downwards and can upwards promote the reset components 3 of valve rod 5.In the embodiment shown in fig. 1, the valve rod actuating mechanism is the cylinder 1 that is arranged on valve rod 5 tops and has the piston rod of extended and withdrawal.Piston rod is positioned at the top of contiguous block 2 and points to the end face of contiguous block 2.Reset components 3 is for being positioned at the compression spring of contiguous block 2 belows.When the piston rod as the cylinder 1 of valve rod actuating mechanism stretches out, the end face of piston rod pushing contiguous block 2, the reset force that makes progress that can overcome reset components 3 is pushed to off position downwards with valve rod 5.When valve rod 5 was in the closed position, the liquid material 20 in the material cylinder 21 can not flow out through liquid outlet 81.When the piston rod of cylinder 1 was withdrawn, piston rod broke away from the end face of contiguous block 2, and the reset force of Bringing-back mechanism 3 makes valve rod 5 be moved upwards up to the open position.When valve rod 5 was in the open position, the liquid material 20 in the material cylinder 21 can flow out from the liquid ebb interval between the inner peripheral surface of the outer peripheral face of valve rod 5 lower ends and liquid outlet 81.
Obviously, the valve rod actuating mechanism is not limited to cylinder shown in Figure 11, also it can be configured to the unidirectional promotion member that cam, crank block etc. can promote valve rod 5 downwards.Reset components 3 also is not limited to compression spring shown in Figure 1, can also adopt the extension spring that is arranged on above the contiguous block 2 or as the elastic element of the other types of compression spring and extension spring, for example the packing ring of sheet spring, air bellow, elastically deformable etc.
With reference to Fig. 1, further, can be provided with valve rod receiving opening 51 in the bottom opening 52 corresponding positions of material cylinder 21 tops and material cylinder 21, one end (upper end) of valve rod 5 passes valve rod receiving opening 51 and stretches out in outside the material cylinder 21, the other end of valve rod 5 (lower end) passes the bottom opening 52 of described material cylinder 21 and stretches into liquid outlet 81 (when the bottom of valve seat 8 and material cylinder 21 forms as one, stretching into liquid outlet).The part that is positioned at material cylinder 21 at valve rod 5 is arranged with seal bellows 4.One end of seal bellows 4 is sealingly fastened in the top inner surface of described material cylinder 21, and the other end sealing and fixing of seal bellows 4 is on the outer surface of valve rod 5.As shown in Figure 1, with respect to the inside face sealed engagement at material cylinder 21 tops, the other end of seal bellows 4 is with respect to the outer surface sealed engagement of valve rod 5 around valve rod receiving opening 51 for an end of seal bellows 4.
Compare with the liquid filling device that existing valve rod is built-in, the another improvement of electronic type liquid filling device of the present utility model is, on the part that is positioned at material cylinder 21 of valve rod 5, seal bellows 4 is set, and because the two ends of seal bellows 4 are respectively with respect to the top inner surface of material cylinder 21 and the outer surface sealed engagement of valve rod 5, therefore seal bellows 4 can with from material cylinder 21 outsides from valve rod receiving opening 51 with the impurity screening that enters between valve rod 5 outer surfaces outside material cylinder 21, avoided the interior liquid material 20 of foreign matter contaminated material cylinder 21.
The lower end of valve rod 5 further is formed with flange part 53, and this flange part 53 is housed in the bottom opening 52 and liquid outlet 81 of material cylinder 21.As shown in Figure 1, these flange part 53 inner hollow, and the hollow space of flange part 53 is communicated with the hollow space of valve rod 5.Muffler 14 for example can be by realizing in the hollow space that the upper end of muffler 14 is inserted flange part 53 with being connected of valve rod 5.The outer peripheral face of flange part 53 can form the liquid leakproof fit with the inner peripheral surface of liquid outlet 81.When the inner peripheral surface of the outer peripheral face of flange part 53 and liquid outlet 81 each other during the liquid leakproof fit, liquid outlet 81 is closed, and the liquid materials 20 in the material cylinder 21 can't flow out from liquid outlet 81.Further, the lower surface of flange part 53 can be formed outstanding downwards outer conical surface, and correspondingly on the inner peripheral surface of liquid outlet 81, form outstanding downwards, can with the leakproof fit internal conical surface of lower surface liquid of flange part 53.Further, sealing arrangement 10 can also be set on the lower surface of flange part 53, seal ring for example is so that further guarantee liquid leakproof fit between the internal conical surface of the lower surface of above-mentioned flange part 53 and liquid outlet 81.
Further, flange part 53 is configured such that valve rod 5 can overcome the reset force of Bringing-back mechanism 3 when during filling liquid bottle explosion taking place and move to off position automatically.For example, with flange part 53 be configured to make its upper surface with respect to the size of its lower surface make gravity sum that back pressure gas and liquid material 20 act on downward pressure on this upper surface and valve rod 5 (comprising flange part 53) greater than the reset force that makes progress of Bringing-back mechanism 3 when during filling liquid bottle explosion taking place with by the upward pressure sum of atmospheric action on flange part 53 lower surfaces, and act on the power sum that makes progress of flange part 53 lower surfaces less than the reset force of Bringing-back mechanism 3 and back pressure gas during normal can.
Electronic type liquid filling device of the present utility model further comprises electrical control gear, and this electrical control gear is used to control vacuum valve 26, pressure-relief valve 17, irritates the opening and closing of valve 28 and flood irrigation valve 27 soon.This electrical control gear also may command valve rod actuating mechanism promotes valve rod 5 downwards and leaves valve rod 5.For embodiment shown in Figure 1, the piston rod of electrical control gear control cylinder 1 stretches out and withdraws.
Electronic type liquid filling device of the present utility model comprises that further the vessel port that is used to make liquid container 15 aims at the aligning gear of liquid outlet 81 and be used to make the container lifting mechanism of liquid container 15 with respect to liquid outlet 81 liftings.
As shown in Figure 1, aligning gear comprises at the centering between valve seat 8 and the liquid container 15 cover 12, is fixedly set in cam 7, the roller 6 that can engage with cam 7 on the fixed part of electronic type liquid-filling machine and is used to guide the pilot bar 23 of aligning gear with respect to liquid outlet 81 up-and-down movements, and wherein centering cover 12 and roller 6 are fixedly attached to pilot bar 23 respectively.When rotating to, the rotating disc of electronic type liquid-filling machine roller 6 is engaged and when rolling on cam 7, aligning gear can rise or descend with its centering cover 12, roller 6 and pilot bar 23 with cam 7 with cam 7.When roller 6 and cam 7 were disengaged, centering cover 12, roller 6 and pilot bar 23 fell because of the deadweight effect.Selectively, on the inner peripheral surface of centering cover 12, bottleneck seal ring 11 is set, further to guarantee the sealing between liquid container 15 oral areas and the centering cover 12.
The container lifting mechanism comprise bottle supporting cylinder cam (not shown) and can with the bottle supporting cylinder 16 of above-mentioned bottle supporting cylinder cam engagement.When rotating disc rotates, bottle supporting cylinder 16 and bottle supporting cylinder cam engagement and rolling thereon, thus rise or descend with respect to liquid filling device, rise or decline with respect to the electronic type liquid filling device thereby drive liquid container 15.
Selectively, the electronic type liquid filling device also can comprise be used to detect the bottle explosion detecting device whether explosion (hereinafter to be referred as " bottle explosion ") takes place as the glass bottle of liquid container 15 during can.This bottle explosion detecting device can be by adopting prior art method for detecting position, power method of inspection etc. can detect aligning gear whether during can the unexpected method that falls determine whether to take place bottle explosion.
The working process of electronic type liquid filling device is described in chronological order below in conjunction with accompanying drawing.
(1) advances bottle
Before can material 20, electrical control gear makes air valve, vacuum valve 26 for example shown in Figure 1, irritate valve 28, flood irrigation valve 27 and pressure-relief valve 17 these four air valves soon and close, make the valve rod actuating mechanism that valve rod 5 is pushed into off position simultaneously, for example stretch out and valve rod 5 is pushed into off position by the piston rod that makes cylinder shown in Figure 11.
When electronic type liquid filling device during with the rotation of the rotating disc of electronic type liquid-filling machine, roller 6 beginnings engage with cam 7 and rise along cam 7, make centering cover 12 rise, so that subsequently liquid container 15 is shifted onto on the bottle supporting cylinder 16 by the container pushing mechanism (not shown) of electronic type liquid-filling machine.Along with rotating disc is rotated further, bottle supporting cylinder 16 rises along bottle supporting cylinder cam, and then is being with liquid container 15 to rise.In the process that bottle supporting cylinder 16 rises, the oral area of liquid container 15 begins against aligning gear, particularly against the lower end of bottleneck seal ring 11, and then the parts of drive aligning gear, for example bottleneck seal ring 11, centering cover 12, pilot bar 23 and roller 6 rise together, till the upper end of the bottleneck seal ring 11 of aligning gear and liquid outlet 81 compress, this moment by the oral area of liquid container 15 via aligning gear and liquid outlet 81 liquid leakproof fits, thereby form a fully enclosed space by liquid container 15 and liquid outlet 81, as shown in Figure 3.
(2) container vacuumizes
Electrical control gear is opened vacuum valve 26 subsequently, and the air in the liquid container 15 is extracted to vacuum chamber 18 via evacuation passageway and vacuum valve 26.The liquid material 20 that remains in the evacuation passageway after the last can is drawn out of when vacuumizing.Electrical control gear cuts out vacuum valve 26 behind the time-delay certain hour.
(3) container inflation back pressure
After vacuum valve 26 cuts out, electrical control gear is opened fast filling valve 28, keeping the back pressure gas of certain pressure irritates valve 28 and waits pressure passageway to enter liquid container 15 inside through fast from back pressure cavity 22, make air pressure and the back pressure cavity 22 interior air pressure in the liquid container 15 reach unanimity, produce foam to prevent gas contained in the material 20 from pouring process, separating out.
According to the type of institute's filling liquid material 20, can select only once to vacuumize and inflate backpressure operation, perhaps repeatedly vacuumize and inflate backpressure operation.When needs repeatedly vacuumize and inflate back pressure, closing fast filling valve 28 at the fast valve 28 of irritating after opening Preset Times, repeat the above-mentioned backpressure operation that vacuumizes and inflate then.Finish vacuumize for the last time and inflate backpressure operation after, fast filling valve 28 is stayed open, the pressure in this moment liquid container 15 and back pressure cavity 22 interior pressure equate.When only once vacuumizing and inflating backpressure operation, this time vacuumizes identical with the last operation that repeatedly vacuumizes and inflate backpressure operation with the concrete operations of inflating back pressure, therefore followingly will only introduce the situation that repeatedly vacuumizes and inflate backpressure operation.
(4) the quick can of material
Open fast the filling after valve 28 Preset Times the last time, cancellation valve rod actuating mechanism actuating to valve rod 5, for example make the piston rod withdrawal of cylinder 1, mechanism 3 upwards is pushed to the open position and makes liquid outlet 81 unlatchings thereby valve rod 5 is reset, and begins to carry out quick can.Liquid material 20 flow through successively liquid outlet 81, aligning gear and muffler 14, and in inwall influent container 15 inside of the shunting action lower edge liquid container 15 that is arranged on the shunt umbrella 13 on the muffler 14.Meanwhile, the gas in the liquid container 15 flow back in the back pressure cavity 22 through waiting pressure passageway and the fast valve 28 of irritating.
(5) material can at a slow speed
After certain hour was carried out in can fast, electrical control gear cut out fast filling valve 28, and flood irrigation valve 27 is opened, and begins to carry out can at a slow speed.Because effective air communication of flood irrigation valve 27 is crossed sectional area and is crossed sectional area less than fast effective air communication of irritating valve 28, the gas of getting back in the back pressure cavity 22 by flood irrigation valve 27 in unit time reduces, thereby cause being filled to the liquid material 20 corresponding minimizings in the liquid container 15, gas is difficult for separating out in filling speed reduction, the material, controls filling accuracy easily.And also can further help the raising of filling accuracy eliminating gradually during the can at a slow speed at the bubble that produces during the quick can.
When the liquid level in the liquid container 15 rose to the lower end mouth of pipe of muffler 14, the gas escape routes in the liquid container 15 were plugged, so form an air chamber between the liquid level of lower surface, liquid outlet 81 and the liquid container 15 of valve rod 5.In order to satisfy the balance of can gas-liquid systems pressure, liquid material 20 continues dirty, and the pressure of air chamber raises, and liquid material 20 is pressed in the hollow space of muffler 14 and valve rod 5.When the pressure of the liquid bottom in the liquid level in the hollow space of muffler 14 and valve rod 5 rises to the pressure that makes mouth of pipe place, muffler 14 lower end and material cylinder 21 was identical, gas-liquid systems pressure reached balance, and liquid material stops to flow, and filling liquid finishes.At this moment, the lower end mouth of pipe of muffler 14 (being an end of evacuation passageway) is positioned at below the liquid level of liquid container 15, and an end of discharge channel, promptly that end of the close liquid container 15 of discharge channel is positioned at the liquid level top of liquid container 15, as shown in Figure 3.
After the predefined filling time of process, electrical control gear makes the valve rod actuating mechanism that valve rod 5 is pushed into off position, and flood irrigation valve 27 cuts out.
(6) container release
When the electronic type liquid filling device rotates near the bottle outlet position with rotating disc, electrical control gear is opened pressure-relief valve 19, gas in the liquid container 15 slowly is discharged to release chamber 19 via discharge channel and pressure-relief valve 17, and the pressure in the liquid container 15 drops to barometric pressure gradually.Liquid material 20 in the hollow space of muffler 14 and valve rod 5 also falls in the liquid container 15 thereupon.Because the liquid level of the liquid material 20 in the material cylinder 21 remains unchanged, under the certain situation of muffler 14 length, liquid volume when reaching the gas-liquid systems equilibrium of pressure in the hollow space of influent container 15 and muffler 14 and valve rod 5 is constant, therefore the volume that finally enters the liquid material 20 in the liquid container 15 is also corresponding constant, can guarantee filling accuracy.When reaching can apart from the different electrolyte level of liquid container 15 oral areas, only need by changing the muffler 14 of different length, it is very convenient to operate.
Because under the state that filling liquid finishes, that end of the close liquid container 15 of discharge channel (being an end of discharge channel) is positioned at the liquid level top of liquid container 15, be not have liquid to exist in the discharge channel, therefore in stress-relief process, can not occur of the prior artly separating out the problem that foam stops up discharge channel, can realize release rapidly, fully because of liquid.
(7) bottle outlet
When the electronic type liquid filling device rotated to the bottle outlet position with rotating disc, bottle supporting cylinder 16 descended along bottle supporting cylinder cam, and liquid container 15 descends with bottle supporting cylinder 16.This moment, roller 6 did not engage with cam 7 as yet, thereby thereby the centering cover 12 that is against on the liquid container 15 is also descended with bottle supporting cylinder 16 to be separated with the electronic type liquid filling device.Roller 6 begins to engage with cam 7 and rises along cam 7 then, and the pilot bar 23, centering cover 12 and the bottleneck seal ring 11 that drive aligning gear rise together, makes centering cover 12 and bottleneck seal ring 11 break away from liquid container 15.At last, by the container pushing mechanism liquid container 15 is pushed away bottle supporting cylinder 16.
(8) operation during bottle explosion
When liquid container 15 was glass bottle, if the bottle explosion phenomenon of glass bottle explosion has taken place in pouring process, the pressure in the liquid container 15 can be dropped rapidly to barometric pressure.At this moment the restoring force that makes progress greater than Bringing-back mechanism 3 of back pressure gas and the liquid material 20 gravity sum that acts on downward power on the upper surface of flange part 53 and valve rod 5 (comprising flange part 53) and atmospheric action are in the power sum that makes progress of flange part 53 lower surfaces, therefore valve rod 5 is pushed downward to off position, thereby close liquid outlet 81, avoid liquid material to gush in a large number from liquid outlet 81.
Meanwhile, the parts of aligning gear (for example centering cover 12, pilot bar 23 and roller 6) fall automatically because of the support that loses liquid container 15.The bottle explosion detecting device can be by detecting aligning gear parts fall the generation that detects bottle explosion, and send detection signal to electrical control gear, make the air valve of electronic type liquid filling device by the latter, for example vacuum valve 26, pressure-relief valve 17, irritate valve 28 soon and flood irrigation valve 27 all cuts out, and make the valve rod actuating mechanism actuate valve rod 5 simultaneously and it is maintained in its closed position reliably, thereby further guaranteed the reliability of electronic type filling apparatus.
Although in conjunction with the embodiments the utility model is described above, the utility model is not limited to the embodiment that is introduced, and can also make various variations and combination under the prerequisite that does not break away from scope of the present utility model.
