Description

Fluid Filling Device {FLUID FILLING DEVICE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a fluid filling apparatus for transferring and filling a liquid or paste-like fluid into a filling container. The present invention relates to, for example, transfer of a fluid such as an epoxy resin, which has been agitated and degassed by a mixer, into a filling container such as a syringe while defoaming. It relates to a fluid filling device for filling.

For example, when applying a fluid such as an epoxy resin to a substrate, the raw material composition is stirred and mixed to form a paste-like fluid, the fluid is degassed by removing bubbles in the fluid, and the degassed fluid is transported and filled into a filling container such as a syringe. We offer to use. For example, first, while mixing and mixing the raw material composition in a stirring vessel such as a mixer, while removing air bubbles contained in the raw material, the degassed fluid is transferred to the pressure feeding container, and the fluid is pumped by a piston. The method of filling in a container to be filled is adopted.

11 is a view for explaining an example of a conventional fluid filling method. As shown in FIG. 11, the degassing fluid 32 is accommodated in the pressure feeding container 31 previously. A piston 33 is inserted into the pressure container 31 in order to pump the fluid 32 in the pressure container 31 to the filling container 34 such as a syringe. In addition, a pump 36 for compressed air is connected to the pressure feeding container 31 via a pipe 35. The compressed air pump 36 compresses the air and supplies the air into the pressure vessel 31 so that the piston 33 is driven so that the fluid 32 in the pressure vessel 31 is pumped to the filled container 34 to be filled. do.

However, the above fluid filling method has the following problems.

(1) In the process of conveying the degassed fluid 32 in the stirring vessel from the stirring vessel to the pressure feeding container 31, air tends to enter the degassed fluid 32 and bubbles are easily generated.

(2) In the area where the fluid 32 is transferred from the pressure feeding container 31 to the filling container 34, air from outside is caught in the conveying path of the fluid 32, and air is released into the defoaming fluid 32. It tends to be easily mixed.

(3) After the fluid 32 is transferred from the stirring vessel to the pressure vessel 31, the piston 33 is inserted into the pressure vessel 31 so that residual air is sandwiched between the fluid 32 and the piston 33. There is a fear that the fluid 32 may inflate air in the feeding process. Therefore, careful care and research are required so that residual air is not inserted between the fluid 32 and the piston 33 when the piston 33 is inserted into the pressure feeding container 31.

(4) Smooth filling depending on the viscosity of the fluid 32 when the longitudinal direction of the filled container 34 is vertically arranged and the fluid 32 is transferred and filled from the lower end side of the filled container 34. This is difficult.

(5) Since the number of members constituting the apparatus used for pressure-feeding the fluid 32 into the filling container 34 is large, much effort is required for its maintenance, resulting in an increase in cost. That is, in order to use these members repeatedly, disassembly of the apparatus and cleaning of the members are required, and the fluid 32 attached to the members is wasted. On the other hand, when the used member is discarded once, the running cost increases significantly.

As a related art, Japanese Patent Application Laid-Open No. JP-P2003-201000A discloses a method of conveying and filling a fluid by stirring and degassing a filled container, and a fluid conveying filling device (mixer). The fluid transfer filling device is connected to a stirring vessel that receives fluid and rotates while rotating, a connection port having an opening / closing valve disposed at the lower end on the central axis of the stirring vessel and supplying a fluid in the stirring vessel, and connected to the connection port. And a charged container which follows the rotation and revolution of the stirring vessel and rotates while rotating.

According to the fluid transfer filling apparatus disclosed in JP-P2003-201000A, the problems of (1) to (5) can be solved by using the centrifugal force according to the rotation and the revolution of the stirring vessel and the filling vessel, and congestion of bubbles and the like can be avoided. The fluid can be transferred and filled from the stirring vessel into the filling vessel without fail. However, in order to fill a large amount of fluid into a plurality of syringes at one time using a large-capacity filled container (syringe), a dedicated fluid filling device capable of mounting a large-capacity stirring container and a large-capacity syringe is required.

In such a fluid filling apparatus, when a plurality of syringes having a large capacity of 100 cm 3 or more, such as eight or twelve, are used, the jig becomes large and heavy, and thus there is a material handling problem. Moreover, the number of cleaning parts increased, and there existed a possibility that an operation mistake may arise in the operator who is not used to handling an apparatus.

Accordingly, in view of the above, the present invention provides a fluid filling apparatus that is light in weight so that a large number of large-capacity containers to be filled (syringe, etc.) can be mounted, and reduces the burden on the operator in material handling. For the purpose of

MEANS TO SOLVE THE PROBLEM In order to solve the said subject, the fluid filling apparatus which concerns on one aspect of this invention is fixed to the outer periphery of the rotating shaft with the container in which the stirring nozzle defoaming fluid was received, and the discharge nozzle which discharges the said fluid is formed, A rotor for holding the vessel at an angle within the range of approximately 30 ° to approximately 90 ° with respect to the longitudinal direction of the rotation shaft, and a distributor fixed to one end of the rotation shaft and guiding fluid discharged from the discharge nozzle of the container to the plurality of filled containers And rotating means for rotating the rotor and the dispenser by rotating the rotary shaft, and filling the plurality of filled containers with fluid guided by the dispenser by the centrifugal force generated by the rotation thereof.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described in detail, referring drawings. In addition, the same component is attached | subjected with the same code | symbol, and the overlapping description is abbreviate | omitted.

1 is a partial cross-sectional view showing the structure of a fluid filling apparatus according to a first embodiment of the present invention. The fluid filling apparatus is provided with a rotating shaft 1 which is rotationally driven by a rotating means such as an electric motor 2, a chamber 4 provided with a support part for supporting the rotating shaft 1 so as to be rotatable, and an outer circumference of the rotating shaft 1. A rotor 5 fixed and rotating together with the rotating shaft 1, a distributor 7 fixed to an upper end of the rotating shaft 1 and rotating together with the rotating shaft 1, and a container disposed on the chamber 4 ( 9) and a control unit 17 for controlling each unit.

The container 9 accommodates a liquid or paste-like material (hereinafter referred to as "fluid") 10 such as an epoxy resin stirred and degassed by a mixer, and a discharge nozzle for discharging the fluid 10 is formed at the bottom thereof. have. Although the central axis of the container 9 coincides with the central axis of the rotating shaft 1, the container 9 is fixed on the chamber 4 and does not rotate with the rotating shaft 1, so the load applied to the electric motor 2 is reduced. Can be minimized.

Compressor 14 for compressing and supplying a gas (air or inert gas, etc.) for pressurizing the fluid 10 contained in the container 9 and extruding it from the discharge nozzle, and a regulator 15 for adjusting the flow rate of the gas. And a tube 16 serving as a gas flow path. In that case, the container 9 has a lid 11 formed with a piston 11 disposed above the fluid 10 and a tube connector 13 for introducing a gas supplied through the tube 16. In addition, in this application, a "compressor" is a wide concept including various pressurization pumps.

When the gas compressed by the compressor 14 is supplied into the container 9 through the regulator 15 and the tube 16, the piston 11 is pushed downward by the pressure of the gas and stored in the container 9. The fluid 10 is pressurized and extruded from the discharge nozzle. The pressure for pressurizing the fluid 10 depends on the viscosity and the storage amount of the fluid 10, but a range from about 1 atm to about 3 atm is preferable, and the controller 17 can adjust the regulator 15 by controlling the regulator 15. .

The rotor 5 holds the plurality of syringes (filled containers) 6 at an angle within the range of approximately 30 ° to approximately 90 ° with respect to the longitudinal direction of the rotation shaft 1. Although the number of syringes 6 to be mounted depends on the size of the syringe 6, it is preferable from 2 to several dozen, and it is preferable to arrange | position the several syringe 6 at equal intervals to the periphery of the rotor 5, and is preferable. Do.

The distributor 7 is composed of a distributor body 7a and a plurality of induction tubes 7b attached to the distributor body 7a. In addition, the distributor body 7a and the plurality of induction tubes 7b may be integrally molded. The flow path and the induction tube 7b in the distributor main body 7a are provided according to the number of attachments of the syringe 6. The dispenser 7 serves as a backing plate of the fluid 10 discharged from the discharge nozzle of the container 9 and flows into the plurality of syringes 6 through the flow path and the induction tube 7b in the dispenser main body 7a. 10). In addition, the rotor 5 and the distributor 7 are rotated by rotating the rotary shaft 1, and the fluid guided by the distributor 7 is filled in the plurality of syringes 6 by centrifugal force. .

FIG. 2 is a plan view showing a first embodiment of the distributor shown in FIG. 1, and FIG. 3 is a partial cross-sectional side view of the distributor. In the first embodiment shown in Figs. 2 and 3, the distributor 7 has eight induction tubes 7b, and each induction tube 7b is inclined downwardly at an angle toward the syringe body 7a. Attached. In order to facilitate the flow of the fluid, a tapered surface having an angle of approximately 30 ° to approximately 60 ° with respect to the longitudinal direction of the rotating shaft 1 (FIG. 1) is formed in the upper portion of the flow path in the distributor main body 7a.

4 is a plan view illustrating a second embodiment of the distributor shown in FIG. 1, and FIG. 5 is a side view of the distributor. 6 is a sectional view of the distributor, and FIG. 7 is a plan view in a state where the distributor upper part is separated from the distributor. In the second embodiment shown in FIGS. 4 to 7, the distributor 8 has a distributor lower portion 8a in which the distributor 8 functions as an induction path of the fluid, and an upper portion of the distributor having an opening through which the fluid is injected from the container 9 (FIG. 1). 8b and a plurality of nozzles 8c for injecting fluid into the plurality of syringes. Each nozzle 8c is attached to the dispenser lower portion 8a so as to slope obliquely downward toward the syringe filled with the fluid. As for the inclination angle of the nozzle 8c, about 30 degrees-about 60 degrees are preferable with respect to the longitudinal direction of the rotating shaft 1 (FIG. 1).

6 and 7 the bottom of the distributor bottom 8a is formed in a plane to equalize the flow of fluid and between eight nozzles 8c between the distributor bottom 8a and the distributor top 8b. A distributor inner sidewall 8d is formed radially to divide. Thereby, the eight which are respectively fitted to the two distributor inner sidewalls 8d facing toward the eight nozzles 8c from the center bottom face (diagonal part) 8e enclosed by the distributor inner sidewall 8d in 8 directions. Guide grooves 8f are formed. Moreover, the inlet 8g to the nozzle 8c is formed in the circumferential surface of the distributor lower part 8a. Further, the member constituting the dispenser inner sidewall 8d may be a separate member attached to the dispenser lower portion 8a or the dispenser upper portion 8b or may be a member integrated with the distributor lower portion 8a or the dispenser upper portion 8b. Also good.

When the fluid is introduced (dropped) into the central bottom surface 8e of the lower part of the distributor 8a while rotating the rotary shaft 1 (FIG. 1), the fluid expands by the centrifugal force and flows along the eight guide grooves 8f. The width of each guide groove 8f is set to match the inner diameter of the nozzle 8c at the position reaching the nozzle 8c. In addition, since the inlet 8g to the nozzle 8c is formed at a position higher than the bottom of the lower part of the distributor 8a so as not to block the flow of the fluid, a structure in which the fluid can pass without accumulation is realized.

Although the case where 8 syringes are arrange | positioned in the 1st and 2nd Example was shown as an example, arrangement | positioning and the number of syringes can be changed by making an appropriate deformation | transformation.

Referring back to FIG. 1, when filling the syringe 6 with a very high viscosity (eg, about 500,000 cps), the fluid is placed in the syringe 6 by a strong centrifugal force by placing the syringe 6 approximately horizontally. It is possible to charge, and even if the rotation of the rotor 5 stops after completion of filling, the fluid does not flow back out of the syringe 6 and flow out. On the other hand, when filling the syringe 6 with relatively low-viscosity fluid, it is not necessary to apply centrifugal force, and the syringe does not flow out of the syringe 6 even if the rotation of the rotor 5 stops after the filling is completed. As for the inclination angle of (6), about 30 degrees-about 60 degrees are preferable.

The centrifugal force acting on the fluid at the tip of the induction tube 7b is controlled by the size of the container 9, the size of the syringe 6, and the characteristics such as the viscosity of the fluid, but is preferably about 30 G to 400 kPa. The rotation speed of the rotor 5 and the distributor 7 is adjusted by changing the frequency of the drive signal applied to the electric motor 2 in the control unit 17, for example, by an inverter.

Moreover, you may use the closed vacuum chamber which covers the circumference | surroundings of the rotor 5 and the distributor 7 at least as the chamber 4 so that a bubble may not be re-introduced into the stirred defoaming fluid. In that case, a vacuum pump 3 such as a dry pump or an oil pump is provided at the lower portion of the chamber 4. The vacuum pump 3 discharges the air in the chamber 4 to the outside, and reduces the pressure in the chamber 4 to make it into a vacuum state. In such a case, the degree of vacuum can be freely adjusted based on the vapor pressure characteristic curve or the like using the controller 17 so that the fluid does not boil due to the boiling point of the fluid. In general, the degree of vacuum is sufficient to about 1torr (0.133㎪) to 100torr (13.3㎪).

Next, the operation example of the fluid filling apparatus shown in FIG. 1 is demonstrated. In this example, the above vacuum chamber is used as the chamber 4.

In the preparatory step, the operator stirs and deflates the fluid 10 using a mixer beforehand and injects it into the container 9. Thereafter, the operator inserts the piston 11 into the container 9 and attaches the lid 12 to the upper side of the container 9. Moreover, the operator attaches the some syringe 6 and the dispenser 7 to the rotor 5 beforehand.

When the operator presses the operation start switch, the controller 17 controls the vacuum pump 3 to lower the pressure in the chamber 4. When the predetermined degree elapses and the degree of vacuum reaches, for example, about 10 torr (1.33 kPa), the controller 17 controls the electric motor 2 to rotate the rotating shaft 1. As a result, the rotor 5 and the distributor 7 rotate together with the rotation shaft 1. The control unit 17 can drive the rotating shaft 1 at variable speed by changing the frequency of the drive signal applied to the electric motor 2, for example, by an inverter.

In the stage where the rotational speed of the rotating shaft 1 reaches a predetermined rotational speed, a predetermined centrifugal force, such as 30G (may be smaller depending on viscosity), is generated at the tip of the induction tube 7b. The compressor 14 or the regulator 15 is controlled to supply the gas to the container 9 through 16. The control unit 17 may start the operation of the compressor 14 at this point, may start the operation of the compressor 14 in advance, and may start the supply of gas by controlling the regulator 15. When gas is supplied to the container 9, the piston 11 pressurizes the fluid 10 by the pressure of the gas. The pressure for pressurizing the fluid 10 can be adjusted by the controller 17 controlling the regulator 15.

Accordingly, the fluid 10 in the container 9 is discharged from the discharge nozzle and flows into the distributor 7. The distributor 7 evenly guides the fluid 10 discharged from the discharge nozzle to the plurality of syringes 6 through the plurality of induction tubes 7b. The fluid guided by the dispenser 7 is filled in the plurality of syringes 6 by the centrifugal force generated by the rotation of the rotor 5 and the dispenser 7. In this manner, high-speed, high-density filling of the plurality of syringes 6 can be performed simultaneously in a short time of about 5 minutes, depending on the throughput and viscosity of the liquid, without mixing bubbles in the fluid.

According to the present embodiment, even when filling a large-capacity syringe with fluid, it is only necessary to mount eight or twelve syringes at a time on the rotor, so that the weight can be greatly reduced, and the burden on the operator is heavy. Can be greatly reduced. In addition, since the number of cleaning parts is greatly reduced, there is also a possibility that an operator's mistake of operation may occur. Moreover, since continuous operation is possible only by replacing a syringe, the down time for performing a washing | cleaning operation etc. becomes unnecessary, and productivity improves significantly (for example, 200% or more). In addition, when using a UV sealant (ultraviolet curing sealant) or the like that is easy to gel (fix) when subjected to extreme pressure (intensive load) as the fluid to be filled, the gelation of the fluid is prevented by eliminating the sliding part. It is possible to reduce the occurrence of the defective rate.

Next, a second embodiment of the present invention will be described.

8 is a partial cross-sectional view showing the structure of a fluid filling apparatus according to a second embodiment of the present invention. In 2nd Embodiment, the container 9 which accommodates the fluid 10 is arrange | positioned in the chamber 4, is hold | maintained by the rotor 5, and rotates with the distributor 7. The central axis of the container 9 coincides with the central axis of the rotating shaft 1, whereby the load on the electric motor 2 can be reduced.

In the second embodiment, the container 9 rotates together with the distributor 7 so that it is rotatable and gas can be injected between the tube 16 fixed to the chamber 4 and the cover 12 of the container 9. It is necessary to connect the rotary joint (swivel joint) 18 which exists. Rotary joints (swivel joints) are pipe joints for connecting a plurality of relatively rotating pipes or appliances to each other. The rotary joint 18 introduces the gas supplied from the compressor 14 through the regulator 15 and the tube 16 into the vessel 9. As a result, the piston 11 is pushed downward by the pressure of the gas to pressurize the fluid 10 contained in the container 9 and to extrude it from the discharge nozzle. Other points are the same as in the first embodiment.

According to this embodiment, not only the rotor 5 and the distributor 7 but also the container 9 are stored in the chamber 4, so that the inside of the chamber 4 is kept in a vacuum state to further prevent the mixing of bubbles into the fluid. You can do it.

Next, a third embodiment of the present invention will be described.

9 is a partial cross-sectional view showing the structure of a fluid filling apparatus according to a third embodiment of the present invention. The third embodiment is a modification of the first embodiment to fill a fluid of low viscosity (e.g., 10,000 cps or less).

In the third embodiment, the opening / closing cock 19 is provided in the discharge nozzle of the container 9 in order to prevent the natural outflow of the low viscosity fluid 10. In addition, the container 9 containing the fluid 10 is fixed on the chamber 4 and does not rotate with the distributor 7, so that a rotary joint between the discharge nozzle of the container 9 and the distributor 7 is provided. (Swivel joint) 18 is connected. The rotary joint 18 can reliably introduce the fluid discharged from the discharge nozzle into the distributor 7. Alternatively, the rotary joint 18 may be omitted so that the fluid 10 naturally falls from the container 9 into the distributor body 7a through the opening / closing cock 19 and the piping. Other points are the same as in the first embodiment.

According to the present embodiment, when the low-viscosity fluid is filled into the syringe, it is possible to prevent the fluid from naturally flowing out of the container 9 or the fluid discharged from the discharge nozzle to leak out of the distributor 7.

Next, a fourth embodiment of the present invention will be described.

10 is a partial cross-sectional view showing the structure of a fluid filling apparatus according to a fourth embodiment of the present invention. In the fourth embodiment, a three-way switching valve 20 is provided instead of the regulator 15 shown in FIG. The three-way switching valve 20 has a tube connection 13 formed through the tube 21 or 22 via a tube 21 or 22 (and a vacuum) to discharge gas from the vessel 9 or to introduce gas into the vessel 9. Pump 3] and compressor 14 are selectively connected.

When the pressure in the chamber 4 is lowered, the controller 17 controls the three-way switching valve 20 so that the tube connection 13 is connected to the chamber 4 (and the vacuum pump 3) through the tube 21. To control. Thereby, since the pressure in the container 9 decreases following the pressure in the chamber 4, the fluid 10 in the container 9 can be prevented from dripping into the syringe 6. As a result, mixing of bubbles into the fluid in the syringe 6 does not occur.

Subsequently, when the pressure in the chamber 4 is sufficiently lowered to fill the plurality of syringes 6 with fluid, the control unit 17 causes the tube connection port 13 to be connected to the compressor 14 through the tube 22 in three directions. The switching valve 20 is controlled. As a result, the piston 11 pressurizes the fluid 10 by the pressure of the gas from the compressor 14, and the fluid 10 in the container 9 is guided to the plurality of syringes 6. The control of the three-way switching valve 20 may be performed by the controller 17 according to the operator's operation, but may be automated as follows.

As a first example of the automatic control of the three-way switching valve 20, the fluid filling apparatus may further include a vacuum gauge 23 for measuring the pressure in the chamber 4. The controller 17 is connected in three directions such that the tube connection 13 is connected to the chamber 4 (and the vacuum pump 3) through the tube 21 when the pressure measured by the vacuum gauge 23 is higher than a predetermined value. The switching valve 20 is controlled.

Subsequently, the control unit 17 starts the electric motor 2 to rotate the rotor 5 when the pressure measured by the vacuum gauge 23 becomes lower than a predetermined value, and the tube connection 13 is connected to the tube ( The three-way switching valve 20 is controlled to be connected to the compressor 14 through 22. As a result, the filling of the fluid into the plurality of syringes 6 is started.

As a second example of automatic control of the three-way switching valve 20, the control unit 17 controls the vacuum pump 3 to lower the pressure in the chamber 4, and then the tube until a predetermined time has elapsed. The three-way switching valve 20 is controlled such that the connector 13 is connected to the chamber 4 (and the vacuum pump 3) through the tube 21.

Subsequently, the controller 17 controls the vacuum pump 3 so as to lower the pressure in the chamber 4, and after the predetermined time has elapsed, the electric motor 2 is started to rotate the rotor 5. , The three-way switching valve 20 is controlled such that the tube connection port 13 is connected to the compressor 14 through the tube 22. As a result, the filling of the fluid into the plurality of syringes 6 is started.

According to the fourth embodiment, the fluid 10 can be prevented from dripping into the syringe 6 before the chamber 4 is sufficiently evacuated, thereby preventing the mixing of bubbles into the fluid in the syringe 6. Other points are the same as in the first embodiment. In addition, also in 2nd or 3rd embodiment, you may make it provide the switching valve 20 etc. similarly to 4th Example.
