[0002]

2. Description of the Related Art A series of steps for filling a liquid beverage and a liquid container for beverage after pretreatment such as sterilization and sealing the container are carried out by, for example, connecting a rotary type automatic filling machine and a stoppering machine in series. It has been put to practical use as a connected automatic machine. This conventional example will be described with reference to FIGS. 6 to 13. FIG. 6 is a perspective view of a main part of a liquid filling machine for beverages. In the figure, reference numeral 1 is a liquid filling machine for drinks, and other air such as a filler tank 2, a liquid filling valve 3, a rotary table 4, a lifter 5, a container supply device 6, a container discharge device 7, a filled liquid supply device 8 and a drive device 9. A pressure supply device, a control device, and the like are configured as main functional units. The filler tank 2 is an axially symmetric rotating body having a substantially rectangular cross section and stores the filling liquid 10. The filler tank 2 is integrally supported by a rotary table 4 and rotates about a center column. Liquid filling valve 3
Is a cylindrical open / close valve arranged in the bottom of the filler tank 2 at equal intervals in the circumferential direction, and supplies the filling liquid 10 to the container 11 in a fixed amount in accordance with the rotational movement of the filler tank 2. The lifter 5 is a pedestal of the container 11, is arranged below the axis of each liquid filling valve 3, and reciprocates in the axial direction according to the rotation of the rotary table 4. The supply of the filling liquid is stopped based on the reciprocating movement of the container 11 with respect to the liquid filling valve 3. Further, the container supply device 6 is composed of a supply conveyor 12, a supply star wheel 13, and the like, and is for indexing and supplying the containers 11 continuously fed on the supply conveyor 12 in accordance with the pitch of the liquid filling valve 3.

The container discharging device 7 is a discharging star wheel 1.
4, the discharge conveyor 15 and the like complete the liquid filling process, and the container 11 above the lifter 5 is continuously discharged onto the discharge conveyor 15 in synchronization with the rotation of the filler tank 2. Further, the filling liquid supply device 8 continuously supplies the pretreated filling liquid 10 into the filler tank 2 via the rotary joint to keep the storage amount constant, and the drive device 9 is the rotary table 4 and the container supply device. 6, the container discharge device 7 and the like are driven. Empty container 11 pretreated in this way
Is sent to the container supply device 6, and a fixed amount of the filling liquid 10 is filled from the container discharge device 7, but the unsealed container 11
Are continuously taken out and sent to the enclosing machine 16 in the next step, where the enclosing is completed and further carried to the next processing step.

Here, the structure of the liquid filling valve 3 will be described with reference to FIGS. 7, 8 and 9, and the filling process will be described with reference to FIGS. First, in the case of pressureless filling, as shown in FIG. 7, the internal space B of the vapor phase portion in the filler tank 2 is in equilibrium with the atmospheric pressure via the pressure equalizing hole 18 provided in the tank top plate 17, for example. .. The liquid filling valve 3 includes a hollow member 19 and the hollow member 1.
Another hollow member 21, which is fitted in the hollow portion 20 in the axial direction of 9 so as to be slidable in an airtight manner and has its own hollow portion as a part of the hollow portion 20, and an elastic member 37 between the two members 19, 21. A tubular member 25 having a hollow portion 24 vertically inserted into the hollow portion 20 and extending in the axial direction on a part of the side wall when the hollow portion 24 is closed. It is composed of a cylindrical plug member 39 having an elongated hole 26 communicating therewith. The tube member 25 is supported by a fixed member 27 so as to be relatively stationary with respect to one member 19 of the expandable cylinder 23, and the movable member 29 at one end of the hollow member 21 is expanded and contracted according to expansion and contraction of the expandable outer cylinder 23. With the plug member 39, the hollow portion 20 and the hollow portion 24
A valve means 30 for opening and closing the communication with is constructed, and a seal member 32 is attached to the hollow member 21. The hollow member 19 is fixed to the filler tank 2 by means of stopper members 33 fixed to a large number of holes provided on the bottom plate 34 of the filler tank 2 at equal intervals on the circumference around the rotation axis.

Reference numeral 22 denotes an expanding / contracting means, which comprises a guide tube 35, a displacement regulating member 36 and an elastic member 37. The guide tube 35 is a member that is slidable in the axial direction on the outer surface of the hollow member 19, and is provided with a guide groove 38 that straddles the displacement regulating member 36 in the axial direction.
The displacement regulating member 36 is a protrusion member fixed to the hollow member 19. The maximum length of the expandable outer cylinder 23 is restricted by the engagement relationship between the guide groove 38 and the displacement restricting member 36 which are closed at both ends. The elastic member 37 is the hollow member 1.
9 and an end surface of the hollow member 21 are acting members that increase relative axial displacement of each other when the external force decreases. In this way, the hollow member 21 slides in the axial direction with the hollow member 19 as a guide, while the expansion / contraction means 22 keeps the maximum displacement state in the free state. Reference numeral 31 denotes a centering member, which is provided at the open end of the guide tube 35 of the expansion / contraction means 22 and centers the container 11. Further, the sealing member 32 maintains the airtightness between the internal space A of the container 11 and the internal space B of the filler tank 2.

In automatically filling the beverage liquid, the filling of the beverage liquid such as alcoholic beverages such as liquor and wine or the non-carbonated beverage such as juice is carried out without the pressure of the liquid to be filled, that is, for the beverage. Generally, the head difference of the liquid is used as the driving force. The liquid filling valve 3 configured as described above fills the liquid in the next step. First, the container 11 is received from the container supply device 6, and the lifter 5 having the container 11 mounted thereon rises along the axis of the liquid filling valve 3 in accordance with the rotation of the filler tank 2. If the amount of increase is less than the predetermined amount, the mouth of the container 11 is not in contact with the seal member 32 of the expandable outer cylinder 23. At this time, the guide tube 35 has its own weight and the elastic member 3
The repulsive force of 7 acts and the guide cylinder 35 is in the maximum displacement state.
When the lifter 5 further rises, the mouth of the container 11 is guided by the guide tube 3
After ascending while contacting the centering member 31 attached to the centering member 5 and receiving the centering, the hollow member 21 is contacted with the seal member 32 and resists the reaction force of the elastic member 37 of the expandable outer cylinder 23.
Push up (waiting for filling).

Next, the start of filling will be described. The container 1
At the same time that the mouth of No. 1 contacts the seal member 32, the movable hollow member 21 of the expandable outer cylinder 23 starts to rise. Due to this rise, the closed state of the movable opening 29 by the hollow member 21 and the closed state of the cutout hole 26 by the hollow portion 20 are broken,
Both the hollow portion 20 and the hollow portion 24 are changed into a communication state with the inside of the container 11, the liquid flows in from the hollow portion 20, and the gas in the container 11 flows from the hollow portion 24 to the internal space B of the gas phase portion of the filler tank 2. Begins to leak. Next, when the movable opening 29 further rises to the target liquid level height L of the filling liquid, the filling liquid outlet cross-sectional area increases, and the gas outlet cross-sectional area also increases.
Is almost full maximum. In this way the container 11
While the gas inside is discharged by the pipe member 25, the filling liquid 10 flows into the container 11 by using the liquid column acting on itself as a driving force, and the liquid level height H gradually rises (FIG. 10, FIG. 11, FIG. 12 and 13). When the liquid level height H reaches the movable opening 29, the inflowing liquid rises in the hollow portion 24 of the ventilation pipe member 25,
When the liquid level height X in the filler tank 2 becomes equal to the liquid level, the liquid flow stops. This is the completion of filling (Fig. 1
3). When the filling is completed, the lifter 5 descends, the hollow member 21 of the expandable outer cylinder 23 descends, closes the hollow portion 20 which is the liquid passage and the hollow portion 24 which is the exhaust passage, and returns to the initial state. However, the liquid remains in the hollow portion 24 of the liquid filling valve 3, and a phenomenon occurs in which the liquid drops into the container 11 at the beginning of the liquid filling in the next step. Since the liquid drop at this time becomes pulsating, it is called a breathing phenomenon. On the other hand, the container 11 is discharged by the container discharging device 7 according to the rotation of the filling machine 1. Also, of course, a small amount of gas remains at the mouth of the container 11.

[0008]

The flow of the filling liquid 10 is blocked in the vicinity of the notch hole 26 of the plug member 39, and the shape of the flow path is designed so as to avoid the blockage of the portion. Therefore, the filling liquid 10 flows along the outer wall surface of the plug member 39 into a conical surface jet with a notch in a part and flows into the container 11, while the gas is exhausted from the notch conical surface. However, there was a problem that the surface of the filling liquid was violently foamed during the filling process. Therefore, if this is prevented, the flow of the filling liquid in the container is stabilized, and the jet flow is generally guided to the inner wall surface of the container, but the jet flow or the liquid film flow along the inner wall surface of the container is It was unavoidable that violent turbulence occurred at the interface with the gas as long as the filling was performed at a constant speed or higher. In addition, when filling a beverage at a prescribed speed, the bubbles generated by the contact of this disturbing gas-liquid and the bubbles entrained in the liquid will float up to the liquid surface before long, and a lot of foam will float on the liquid surface. Progresses. Therefore, when the filling progresses and the liquid level of the filling liquid rises, first, the bubbles on the liquid surface
Reach opening 40. And at this time, the filling speed is drastically reduced. It was revealed that this was due to a large discharge resistance of foam in the exhaust passage and a relative decrease in the filling head. The present invention provides a liquid filling valve capable of artificially extinguishing this foam generated during the filling process of a liquid beverage, positively preventing a decrease in filling speed and enabling high-speed filling,
The present invention is intended to provide a liquid filling device using this filling valve.

[0009]

Therefore, according to the present invention, the other hollow member inserted in one hollow member is slidably supported while keeping airtightness in the axial direction, and a fixed opening is provided at one end.
An expandable and contractible outer cylinder having a movable opening at the other end, and an expandable and retractable outer cylinder which is inserted into the outer cylinder and has an opening at one end and a hollow portion having a notch hole at the other end. Along with opening and closing the movable opening and the notched hole according to the amount, the hollow portion of the outer cylinder is partitioned into a double passage, and a ventilation pipe supported by the expandable outer cylinder is provided, and from the hollow portion of the hollow member. A valve means for guiding the filling liquid and filling the container with the liquid discharged from the ventilation pipe, and a vibration at a high frequency in the ultrasonic range provided on the side of the outer wall of the movable part of the expandable outer cylinder in contact with the liquid. And a vibrating means for vibrating, which serves as means for solving the problem. Further, the present invention is an ultrasonic liquid filling valve to a large number of holes provided at equal intervals on the circumference centered on the rotation axis of the bottom surface of the filler tank, and a single vibrating means for vibrating each vibrating means. 2. An oscillating power source is provided, and each oscillating means is selectively connected to an oscillating power source common to a predetermined rotation angle section of the filler tank via an operation timing control means. The ultrasonic vibrating liquid filling valve is used as a means for solving the problem.

[0010]

The ultrasonic vibrating means vibrates the outer wall of the liquid passage of the valve means from the side. This vibration reaches the tip of the valve means and vibrates the air at the mouth of the container. By this vibration, bubbles floating on the liquid surface are hit and destroyed. As a result, it is possible to prevent the exhaust passage from being blocked by bubbles, and prevent the filling speed from decreasing. The vibration frequency f of the vibration source is a high-frequency vibration that far exceeds the natural frequency of the vibration propagation member, for example, the member forming the outer wall. The wave phenomenon propagating at velocity becomes dominant. Since the propagation velocity of this elastic wave is almost determined by the elastic modulus and density of the propagating member, the physical properties can be known by selecting the propagating member. The vibration system can be adjusted so that the part becomes the antinode of vibration. In this way, the surface of the member at the container inlet of the liquid filling valve can be vibrated at high frequency. As a result, the portion vibrates the air in the container, and the sound pressure wave strikes the foam collected on the surface of the filling liquid. This mechanical force breaks the stability of the foam and promotes liquefaction, and suppresses the growth of foam on the surface of the liquid in the container as the liquid is filled. Therefore, the decrease in the liquid filling speed due to the bubble growth is prevented, and the high speed filling becomes possible.

The valve means 41 comprises a telescopic outer cylinder 48 and a ventilation pipe 4.
The expandable outer cylinder 48 is composed of a hollow member 50, one end of which is fixed to the bottom plate 24 of the filler tank 2, and an inner wall surface of the hollow portion 51 of the hollow member 50 is guided and slid in an axially airtight manner. It has a hollow member 55 in which an upper hollow member 52 movably fitted and a lower hollow member 54 having a thin cylindrical portion 53 extending in the longitudinal direction are integrally fastened together in the longitudinal direction. Further, the cylindrical member 56 and the bottomed cylindrical member 58 having the concentric hole 57 at the bottom are screwed together, and the concentric hole 57 is cylindrical so as to be concentric with the outer wall of the thin-walled cylindrical portion 53 of the lower hollow member 54. One end of the member 56 is fixed to the lower hollow member 54 to form a cylindrical support member 59, and an expansion / contraction means 62 including a guide cylinder 60 and an elastic member 61 is provided. The guide tube 60 is a cylindrical member having one end fastened concentrically with the hollow member 50 and having a displacement regulating member 63 on the inner wall at the other end, and guides the outer diameter protrusion 64 of the hollow member 55 by loose fitting. At the same time, the outer diameter protrusion 64 of the hollow member 55 is engaged with the displacement restricting member 63 to restrict the maximum displacement. On the other hand, the elastic member 6
Reference numeral 1 denotes a spring provided so as to unilaterally increase the axial relative displacement between the hollow member 50 and the upper hollow member 52, which may be a compression type at the position shown or a tension type at the opposite position. A ring-shaped elastic member 66 is provided in the hole 57 of the cylindrical member 58.
Is provided to buffer and support the outer wall of the thin-walled cylindrical portion 53. In this way, the hollow member 50, the hollow member 55, the cylindrical support member 59, the guide tube 60, the displacement regulating member 63, and the elastic member 61.
Cooperate with each other to keep the stretched state in a free state, and have a fixed opening 65 at one end and a movable opening 29 at the other end.
8 is composed.

The ventilation pipe 49 has a structure in which the plug member 39 is eccentrically provided at one end of the pipe member 25. One end of the hollow portion 24 of the pipe member 25 is simply opened at the upper opening 68 and communicates with the internal space B of the gas phase portion in the filler tank 2.
Further, the lower part becomes a hollow portion 67, and an outer wall 69 of the hollow portion 67.
The outer circumference circle of is inscribed in the outer circumference circle of the plug member 39.
Further, the hollow portion 67 is provided with a notch 70 extending in the axial direction, and the hollow portion 67 communicates with the outside through the notch 70. The tube member 25 includes the outer wall 69 of the hollow portion 67 and the plug member 3.
The outer peripheral surface of 9 is fixed to one end of the hollow member 50 by a fixing member 71 so as to contact the inner wall surface of the thin cylindrical portion 53 that forms the movable opening 29 of the lower hollow member 54 of the expandable outer cylinder 48. In this way, the telescopic outer cylinder 48 and the ventilation pipe 4
9 cooperates to partition the hollow portion 51 into the hollow portion 24 and the double passage of the hollow portion 51 outside thereof. On the other hand, a retractable outer cylinder 48
The plug member 39 opens and closes the movable opening 29 in accordance with the amount of movement of the hollow member 55, and at the same time, controls the communication between the hollow portion 67 and the outside through a notch hole 70 that communicates with the opening 29.

The centering cup 72 holds the seal member 73 on its free end surface, and is fixed to the free end of the radial direction support member 59 so that the tip of the thin-walled cylindrical member 53 always projects. These members move integrally with the hollow member 55. The vibrating means 42 includes a vibrator 74 and a horn 7.
5, the support member 76, and is connected to the vibration power source 44 by the operation timing control means 45. One end of the horn 75 is a radial threaded annular member integrally fixed to the longitudinal outer wall of the thin-walled cylindrical portion 53 of the lower hollow member 54 constituting the expandable outer cylinder 48 of each valve means 41. An elongated hole 77 formed in the cylindrical support member 59 is passed through the screw portion and fixed integrally. On the other hand, the oscillator 74 is formed by a magnetic circuit in which a coil is wound with a frame-shaped member made of a magnetostrictive material as an iron core in the current type, for example.
If it is a voltage type, a piezoelectric material is used, and the strain of the piezoelectric material according to the electric field strength is used as the exciting force. Further, one end of the vibrator 74 is further integrally connected to the other end of the horn 75 with a screw. Since the assembly of the oscillator 74 and the horn 75 integrally constitutes a vibration system, the node is screwed together and is supported by one end of the support member 76 and the other end is a cylindrical support member having high rigidity. It is fixed to 59 to support the vibration system.

The oscillating power supply 44 is an eccentric voltage source or current source obtained by superimposing a high frequency AC voltage on a DC voltage, for example, and applies an eccentric alternating voltage or current according to the characteristics of the vibrator 74. As a result, the vibrator member causes a mechanical displacement and vibrates at a speed according to the applied frequency. Of course, as the excitation frequency, a frequency that resonates with the natural frequency of the vibrator is selected. If the cross-sectional area of the horn 75 is designed to decrease in the transmission direction, the vibration of the vibrator 74 is amplified and transmitted, and the vibration energy is amplified. In this way, the vibrating means 42 laterally vibrates the thin-walled cylindrical portion 53 of the lower hollow member 54 of the one hollow member 55 of the expandable outer cylinder 48 forming the liquid passage.

The state of vibration at this time is shown in FIGS.
The vibration modes are shown in. When the weight of the thin cylindrical portion 53 is ignored, the vibration system is approximated to the transverse vibration of a simple beam in which one end is fixed, the other end is free, and a position partially inward from the free end is simply supported. The applied vibration propagates back and forth through the beam at a substantially elastic wave velocity a = √ {E / ρ}. Here, E is the Young's modulus of the elastic body Kg / cm ² ρ is the density of the elastic body Kg * s ² / cm ^4, for example, stainless steel is a = about 4900 m / s. Beam length L Circular pipe outer diameter D Wall thickness t Distance of vibration position P from fixed end R X ₁ Distance of support position Q from free end X ₂ is designed appropriately, if fixed end R has nodes, A vibration mode in which the free end Q and the excitation point P are antinodes can be set. Next, FIG. 3 (a)
(D) shows the example of calculation of the following conditions, respectively. L mm t mm D mm mm mode (a) 56 1.5 9-12 secondary (b) 56 1.0 9-12 secondary (c) 96 1.0 10-12 secondary (d) 94 1.5 A plurality of antinodes and nodes of the 9th to 12th order vibrations appear depending on the order of the vibration mode. Therefore, a position suitable for the purpose may be selected.

Further, the vibration applied laterally to the thin-walled cylindrical portion 53 by the vibrating means 42 causes a high-frequency and high-energy sound pressure from the side surface of the tip of the thin-walled cylindrical portion 53 at a high frequency according to the characteristics of the vibrating means 42. That is, ultrasonic waves are emitted into the air. Also the excitation timing vessel 11 the liquid level rises from the rotation angle theta _s of the rotary table 4 the liquid level rises liquid filling is started begins ended, while the rotation angle theta _e of the rotary table 4 the liquid filling is completed If set, from the side surface of the tip of the thin-walled cylindrical portion 53 during the rotation angle θ _se of the turntable 4 corresponding to the liquid filling section, the container 1
The air at the mouth of No. 1 is vibrated at a frequency in the ultrasonic range. The bubbles generated by the liquid filling in this section as in the conventional case are instantly destroyed by the vibration of the ultrasonic waves. In this way, the adverse effect of blocking the exhaust passage with bubbles is eliminated, and a decrease in filling speed is prevented. A large number of valve means 41 are circumferentially arranged at the bottom of the filler tank 2 and rotate. The vibrating means 42 is the valve means 4
Although it is provided corresponding to No. 1, the vibration is required only during θ _se , so the energized state must be controlled according to the table rotation angle θ. 1 of the power supply connection diagram in FIG. 4 and FIG.
Here is an example: The vibration power supply 44 is fixedly provided in the filler tank 2. The power supply connecting means 46 is composed of a slip ring 78 and a slider 79, and connects the power supply 47 and the vibration power supply 44 to supply electric power. Further, each vibrator 74 has one end connected in parallel to the output end of the vibration power supply 44 through the contact of the operation timing control means 45. Further, as shown in FIG. 5, the contacts are, for example, switches arranged at a phase difference of 2π / n with respect to each other on the circumference of the switch mounting member 81 which rotates together with the tank about O-O 'as an axis. 82 and a flat or cylindrical cam 83 fixed to a stationary member, and the lift curve of the cam 83 is selected so that the operating angle range is the rotation angle θ _se . According to this configuration, the vibrator having the arbitrary head is excited by being conducted to the vibration power supply 44 during the filling section of the arbitrary valve means 41, and a single vibration power supply excites a plurality of vibrators. Also, the excitation section should be at least the filling section θ.
If set to _se , the bubbles floating on the liquid surface during this time will be instantly destroyed, and the factor that increases the exhaust resistance will disappear.

[0018]

As described in detail above, according to the present invention, by forcibly eliminating the foam generated along with the liquid filling, the filling speed decrease caused by the flow resistance of the foam appearing in the latter half of the filling can be suppressed. Can be prevented and the filling capacity per unit time is improved. Further, if the processing capacity is to be increased, the filling machine can be rotated at high speed or increased in size, and if the processing capacity is satisfied, downsizing of the filling machine can be expected.
