Description

  The present invention relates to a fluid filling apparatus for transferring and filling a liquid or pasty fluid into a container to be filled, for example, a syringe or the like that has been defoamed by a mixer while the defoamed state of a syringe or the like The present invention relates to a fluid filling device that transfers and fills a container to be filled.

  For example, when applying a fluid such as an epoxy resin to a substrate, the raw material composition is stirred and mixed into a paste-like fluid, and the fluid is defoamed by removing bubbles in the fluid, and the defoamed fluid Is used by being transferred and filled into a filling container such as a syringe. For example, first, while stirring and mixing the raw material composition in a stirring vessel such as a mixer, the defoamed fluid is transferred to a pressure feeding vessel while removing bubbles contained in the raw material, A method of filling a container to be filled by pumping fluid with a piston is employed.

  FIG. 11 is a diagram for explaining an example of a conventional fluid filling method. As shown in FIG. 11, a fluid 32 that has been degassed in advance is stored in the pressure-feeding container 31. In order to pressure-feed the fluid 32 in the pressure-feeding container 31 to the filling container 34 such as a syringe, a piston 33 is inserted into the pressure-feeding container 31. A compressed air pump 36 is connected to the pressure feeding container 31 via a pipe 35. The compressed air pump 36 compresses the air and supplies it into the pressure feeding container 31, whereby the piston 33 is driven, and the fluid 32 in the pressure feeding container 31 is pressure fed to the filling container 34 and filled. .

However, the above fluid filling method has the following problems.
(1) In the process in which the fluid 32 defoamed in the stirring vessel is transferred from the stirring vessel to the pressure feeding vessel 31, air tends to enter the defoamed fluid 32 and bubbles tend to be generated.
(2) In the region where the fluid 32 is transferred from the container 31 for pressure transfer to the filled container 34, the outside air is entrapped in the transfer path of the fluid 32, and the air tends to be mixed into the defoamed fluid 32. .
(3) Since the piston 33 is inserted into the pressure feeding container 31 after the fluid 32 is transferred from the stirring container to the pressure feeding container 31, residual air is sandwiched between the fluid 32 and the piston 33, and in the pressure feeding process. The fluid 32 may entrain air. Therefore, when the piston 33 is inserted into the pressure feeding container 31, careful attention and contrivance are required so that residual air is not sandwiched between the fluid 32 and the piston 33.
(4) When the longitudinal direction of the filling container 34 is arranged vertically and the fluid 32 is transferred and filled from the lower end side of the filling container 34, smooth filling is difficult depending on the viscosity of the fluid 32.
(5) Since the number of members constituting the apparatus used for pressure-filling the fluid 32 into the filling container 34 is large, a lot of labor is required for the maintenance, resulting in an increase in cost. That is, in order to repeatedly use these members, it is necessary to disassemble the device and clean the members, and the fluid 32 attached to the members is wasted. On the other hand, when discarding a member once used, the running cost increases significantly.

  As a related technique, Japanese Patent Application Publication JP-P2003-201000A discloses a method in which a fluid is stirred and degassed and transferred to a container to be filled, and a fluid transfer filling device (mixer). This fluid transfer and filling device is connected to a stirring container that contains a fluid and revolves while rotating, a connection port with an opening / closing valve that is disposed at the lower end on the central axis of the stirring container and supplies the fluid in the stirring container A filling container connected to the mouth and revolving while revolving following the rotation and revolution of the stirring container.

  According to the fluid transfer and filling device disclosed in JP-P2003-201000A, the above problems (1) to (5) can be solved by utilizing the centrifugal force associated with the rotation and revolution of the stirring vessel and the filling vessel. Thus, the fluid can be reliably transferred and filled from the stirring container into the filling container without causing the intake of bubbles or the like. However, in order to fill a large number of fluids into a plurality of syringes at once using a large-capacity filled container (syringe), a dedicated fluid filling that can be equipped with a large-capacity stirring container and a large-capacity syringe A device is required.

In such a fluid filling device, when a large number of syringes having a large capacity of 100 cm ³ or more are used at a time, such as eight or twelve, jigs become large and heavy, so there is a problem in material handling. there were. In addition, the number of cleaning parts increases, and there is a possibility that an operational error may occur for an operator who is not used to handling the apparatus.

  Accordingly, in view of the above points, the present invention provides a fluid filling device that is light-weighted so that a large number of large-capacity containers (syringes and the like) can be attached, and that reduces the burden on the operator on material handling. With the goal.

  In order to solve the above-described problem, a fluid filling apparatus according to one aspect of the present invention includes a container in which an agitated and defoamed fluid is stored and a discharge nozzle that discharges the fluid is formed, and is fixed to the outer periphery of a rotating shaft. A rotor that holds a plurality of containers to be filled at an angle within a range of approximately 30 ° to approximately 90 ° with respect to the longitudinal direction of the rotating shaft, and is fixed to one end of the rotating shaft and discharged from the discharge nozzle of the container. A distributor for guiding a fluid to be filled into a plurality of filled containers, and a rotor and a distributor by rotating a rotating shaft, and a centrifugal force generated by the rotation of the distributor causes the fluid induced by the distributor to Rotating means for filling the filling container.

  According to one aspect of the present invention, the rotor that holds the plurality of filled containers at a predetermined angle and the distributor that guides the fluid discharged from the discharge nozzle of the container to the plurality of filled containers are rotated. The fluid induced by the distributor can be filled into a plurality of filled containers by the centrifugal force generated by the rotation thereof. As a result, it is possible to provide a fluid filling apparatus that is light weighted without using a large and heavy jig so that a large number of containers to be filled can be mounted, and that reduces the burden on the operator in material handling. Is possible.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, the same referential mark is attached | subjected to the same component and the overlapping description is abbreviate | omitted.
FIG. 1 is a partial cross-sectional view showing the structure of the fluid filling apparatus according to the first embodiment of the present invention. This fluid filling apparatus is fixed to the outer periphery of the rotating shaft 1, which is provided with a rotating shaft 1 that is rotationally driven by rotating means such as an electric motor 2, a support portion that rotatably supports the rotating shaft 1, and the rotating shaft 1. The rotor 5 that rotates together with the rotating shaft 1, the distributor 7 that is fixed to the upper end of the rotating shaft 1 and rotates together with the rotating shaft 1, the container 9 that is disposed on the chamber 4, and each part is controlled. And a control unit 17.

  The container 9 stores a liquid or paste-like material (hereinafter referred to as “fluid”) 10 such as an epoxy resin that has been agitated and defoamed by a mixer, and a discharge nozzle for discharging the fluid 10 is formed in the lower part. . The central axis of the container 9 coincides with the central axis of the rotating shaft 1, but the container 9 is fixed on the chamber 4 and does not rotate together with the rotating shaft 1, so that the load applied to the electric motor 2 is minimized. Can be limited.

  In order to pressurize the fluid 10 stored in the container 9 and push it out from the discharge nozzle, a compressor 14 that compresses and supplies gas (air, inert gas, etc.), a regulator 15 that adjusts the flow rate of the gas, and gas You may make it provide the tube 16 used as this flow path. In that case, the container 9 includes a piston 11 disposed on the upper side of the fluid 10 and a lid 12 formed with a tube connection port 13 for introducing a gas supplied via the tube 16. In the present application, the “compressor” is a broad concept including various pressurizing 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 to pressurize the fluid 10 stored in the container 9. Extrude from the discharge nozzle. The pressure for pressurizing the fluid 10 depends on the viscosity and the storage amount of the fluid 10, but is preferably in a range from approximately 1 atm to approximately 3 atm, and can be adjusted by the controller 17 controlling the regulator 15.

  The rotor 5 holds a plurality of syringes (filled containers) 6 at an angle within a range of approximately 30 ° to approximately 90 ° with respect to the longitudinal direction of the rotary shaft 1. Depending on the size of the syringe 6, the number of syringes 6 to be mounted is preferably from 2 to several tens, and a plurality of syringes 6 are preferably arranged at equal intervals around the rotor 5.

  The distributor 7 includes a distributor main body 7a and a plurality of guide tubes 7b attached to the distributor main body 7a. The distributor main body 7a and the plurality of guide tubes 7b may be integrally formed. The flow paths and the guide tubes 7b in the distributor main body 7a are provided according to the number of syringes 6 attached. The distributor 7 serves as a tray for the fluid 10 discharged from the discharge nozzle of the container 9, and guides the fluid 10 to the plurality of syringes 6 through the flow path and the guide tube 7b in the distributor main body 7a. Furthermore, when the electric motor 2 rotates the rotating shaft 1, the rotor 5 and the distributor 7 rotate, and the fluid induced by the distributor 7 is filled in the plurality of syringes 6 by centrifugal force.

  2 is a plan view showing a first embodiment of the distributor shown in FIG. 1, and FIG. 3 is a partial sectional side view of the distributor. In the first embodiment shown in FIGS. 2 and 3, the distributor 7 has eight guide tubes 7b, and each guide tube 7b is inclined obliquely downward toward the syringe. It is attached to the distributor main body 7a. In order to smooth the flow of the fluid, a tapered surface having an angle of about 30 ° to about 60 ° with respect to the longitudinal direction of the rotating shaft 1 (FIG. 1) is formed on the upper portion of the flow path in the distributor main body 7a. Is formed.

  4 is a plan view showing a second embodiment of the distributor shown in FIG. 1, and FIG. 5 is a side view of the distributor. FIG. 6 is a cross-sectional view of the distributor, and FIG. 7 is a plan view of the distributor with the upper part of the distributor removed. In the second embodiment shown in FIGS. 4 to 7, the distributor 8 is formed with a distributor lower part 8a that functions as a fluid guiding path, and an opening into which fluid is injected from the container 9 (FIG. 1). The distributor upper portion 8b and a plurality of nozzles 8c for injecting fluid into a plurality of syringes. Each nozzle 8c is attached to the distributor lower part 8a so as to be inclined obliquely downward toward the syringe filled with fluid. The inclination angle of the nozzle 8c is preferably about 30 ° to about 60 ° with respect to the longitudinal direction of the rotary shaft 1 (FIG. 1).

  Referring to FIGS. 6 and 7, in order to equalize the fluid flow, the bottom of the distributor lower part 8a is formed in a plane, and eight nozzles 8c are provided between the distributor lower part 8a and the distributor upper part 8b. A distributor inner side wall 8d is provided radially so as to partition the space. As a result, eight guides each sandwiched by two opposing distributor inner side walls 8d from the central bottom face (shaded portion) 8e surrounded by the eight-way distributor inner side walls 8d toward the eight nozzles 8c. A groove 8f is formed. A guide port 8g to the nozzle 8c is formed on the circumferential surface of the distributor lower part 8a. The member constituting the distributor inner side wall 8d may be a separate member attached to the distributor lower part 8a or the distributor upper part 8b, or may be a member integrated with the distributor lower part 8a or the distributor upper part 8b. .

When the fluid flows in (drops) into the central bottom surface 8e of the distributor lower part 8a while rotating the rotating shaft 1 (FIG. 1), the fluid spreads by centrifugal force and flows along the eight guide grooves 8e. go. The width of each guide groove 8e is set to coincide with the inner diameter of the nozzle 8c at the position reaching the nozzle 8c. Further, since the guide port 8g to the nozzle 8c is formed at a position higher than the bottom of the distributor lower part 8a so as not to block the flow of the fluid, a structure in which the fluid can pass without stagnation is realized.
In the first and second embodiments, the case where eight syringes are arranged is shown as an example, but the arrangement and number of syringes can be changed with appropriate modifications.

  Referring to FIG. 1 again, when the syringe 6 is filled with a fluid having an extremely high viscosity (for example, about 500,000 cps), the syringe 6 is disposed substantially horizontally, so that the fluid is injected into the syringe 6 by a strong centrifugal force. The fluid does not flow backward from the syringe 6 even if the rotation of the rotor 5 stops after the filling is completed. On the other hand, when the syringe 6 is filled with a relatively low-viscosity fluid, it is not necessary to apply a centrifugal force so that the fluid does not flow out of the syringe 6 even if the rotation of the rotor 5 is stopped after filling. The inclination angle of the syringe 6 is preferably about 30 ° to about 60 °.

  The centrifugal force acting on the fluid at the tip of the guide tube 7b is adjusted 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 30G to 400G. The rotational speeds of the rotor 5 and the distributor 7 are adjusted by the controller 17 by changing the frequency of the drive signal applied to the electric motor 2 by, for example, an inverter.

  Further, a sealed vacuum chamber that covers at least the periphery of the rotor 5 and the distributor 7 may be used as the chamber 4 so that bubbles do not re-mix into the stirred and defoamed fluid. In that case, a vacuum pump 3 such as a dry pump or an oil pump is provided in the lower portion of the chamber 4. The vacuum pump 3 discharges the air in the chamber 4 to the outside, so that the pressure in the chamber 4 is reduced to a vacuum state. In this case, the degree of vacuum can be freely adjusted based on the vapor pressure characteristic curve or the like using the control unit 17 so that the fluid does not boil due to the boiling point of the fluid. Generally, a degree of vacuum of about 1 torr (0.133 kPa) to 100 torr (13.3 kPa) is sufficient.

Next, an operation example of the fluid filling apparatus shown in FIG. 1 will be described. In this example, the vacuum chamber as described above is used as the chamber 4.
In the preparation stage, the operator uses the mixer in advance to stir and degas the fluid 10 and inject 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. The operator attaches a plurality of syringes 6 and a distributor 7 to the rotor 5 in advance.

  When the operator presses the operation start switch, the control unit 17 controls the vacuum pump 3 so as to decrease the pressure in the chamber 4. When the predetermined time has elapsed and the degree of vacuum reaches, for example, about 10 torr (1.33 kPa), the control unit 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 rotating shaft 1. The control unit 17 can drive the rotary shaft 1 at a variable speed by changing the frequency of the drive signal applied to the electric motor 2 by, for example, an inverter.

  When the rotational speed of the rotary shaft 1 reaches a predetermined rotational speed and a predetermined centrifugal force, for example, a centrifugal force of about 30 G (may be smaller depending on the viscosity) is generated at the tip of the guide tube 7b, The control unit 17 controls the compressor 14 or the regulator 15 so as to supply gas to the container 9 through the tube 16. The controller 17 may start the operation of the compressor 14 at this time, or may start the operation of the compressor 14 in advance and start the gas supply 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 control unit 17 controlling the regulator 15.

  Thereby, the fluid 10 in the container 9 is discharged from the discharge nozzle and flows into the distributor 7. The distributor 7 equally guides the fluid 10 discharged from the discharge nozzle to the plurality of syringes 6 via the plurality of guide tubes 7b. The plurality of syringes 6 are filled with the fluid induced by the distributor 7 due to the centrifugal force generated by the rotation of the rotor 5 and the distributor 7. In this way, high-speed and high-density filling with respect to the plurality of syringes 6 can be simultaneously performed in a short time of about 5 minutes, depending on the liquid throughput and viscosity, without mixing bubbles in the fluid. it can.

  According to the present embodiment, even when a large capacity syringe is filled with fluid, it is only necessary to attach 8 or 12 syringes to the rotor at a time, so that the weight can be significantly reduced, and the operator for the load can be reduced. Can be greatly reduced. In addition, since the number of cleaning parts is greatly reduced, the risk of operator error is reduced. Furthermore, since continuous operation is possible only by exchanging the syringe, no downtime is required for performing a cleaning operation or the like, and the productivity is greatly improved (for example, 200% or more). In addition, when using a UV sealant (ultraviolet curing sealant) that easily gels (solidifies) when subjected to extreme pressure load (concentrated load) as the fluid to be filled, the fluid can be eliminated by eliminating the sliding portion. It is possible to prevent gelation and drastically reduce the occurrence of defective rate.

Next, a second embodiment of the present invention will be described.
FIG. 8 is a partial cross-sectional view showing the structure of the fluid filling apparatus according to the second embodiment of the present invention. In the second embodiment, a container 9 that stores the fluid 10 is disposed in the chamber 4, is held by the rotor 5, and rotates together with the distributor 7. The central axis of the container 9 coincides with the central axis of the rotary shaft 1, thereby reducing the load on the electric motor 2.

  In the second embodiment, since the container 9 rotates together with the distributor 7, a rotary joint that can rotate and inject gas between the tube 16 fixed to the chamber 4 and the lid 12 of the container 9. (Swivel joint) 18 needs to be connected. A rotary joint (swivel joint) is a pipe joint for connecting a plurality of relatively rotating pipes or devices to each other. The rotary joint 18 introduces gas supplied from the compressor 14 via the regulator 15 and the tube 16 into the container 9. As a result, the piston 11 is pushed downward by the pressure of the gas, and the fluid 10 stored in the container 9 can be pressurized and pushed out from the discharge nozzle. The other points are the same as in the first embodiment.

  According to this embodiment, since not only the rotor 5 and the distributor 7 but also the container 9 is stored in the chamber 4, it is possible to further prevent bubbles from being mixed into the fluid by keeping the chamber 4 in a vacuum state. It becomes possible.

Next, a third embodiment of the present invention will be described.
FIG. 9 is a partial cross-sectional view showing the structure of the fluid filling apparatus according to the third embodiment of the present invention. The third embodiment is a modification of the first embodiment in order to fill a fluid having a low viscosity (for example, 10,000 cps or less).

  In the third embodiment, an open / close cock 19 is provided in the discharge nozzle of the container 9 in order to prevent the low-viscosity fluid 10 from naturally flowing out. Further, since the container 9 for storing the fluid 10 is fixed on the chamber 4 and does not rotate together with the distributor 7, a rotary joint (swivel joint) is provided between the discharge nozzle of the container 9 and the distributor 7. 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, and the fluid 10 may naturally fall from the container 9 into the distributor main body 7a through the open / close cock 19 and the piping. The other points are the same as in the first embodiment.

  According to this embodiment, when filling a low-viscosity fluid into the syringe, the fluid naturally flows out from the container 9 and prevents the fluid discharged from the discharge nozzle from leaking out of the distributor 7. It becomes possible.

Next, a fourth embodiment of the present invention will be described.
FIG. 10 is a partial cross-sectional view showing the structure of the fluid filling apparatus according to the 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 is connected to the chamber 4 (and the vacuum pump 3) via a tube 21 or 22 through a tube connection port 13 formed for discharging gas from the container 9 or introducing gas into the container 9. One of the compressors 14 is selectively connected.

  When the pressure in the chamber 4 is decreased, the control unit 17 controls the three-way switching valve 20 so that the tube connection port 13 is connected to the chamber 4 (and the vacuum pump 3) via the tube 21. . Thereby, since the pressure in the container 9 decreases following the pressure in the chamber 4, it is possible to prevent the fluid 10 in the container 9 from dripping into the syringe 6. As a result, bubbles are not mixed into the fluid in the syringe 6.

  Next, when the pressure in the chamber 4 is sufficiently reduced and the plurality of syringes 6 are filled with fluid, the control unit 17 connects the tube connection port 13 to the compressor 14 via the tube 22. The three-way switching valve 20 is controlled. As a result, the piston 11 pressurizes the fluid 10 by the gas pressure 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 control unit 17 according to the operation of the operator, but may be automated as follows.

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

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

  As a second example relating to the automatic control of the three-way switching valve 20, the controller 17 controls the tube connection port until a predetermined time elapses after the vacuum pump 3 is controlled so as to reduce the pressure in the chamber 4. The three-way switching valve 20 is controlled so that 13 is connected to the chamber 4 (and the vacuum pump 3) via the tube 21.

  Next, the control unit 17 starts the electric motor 2 to rotate the rotor 5 after a predetermined time has passed since the vacuum pump 3 was controlled so as to reduce the pressure in the chamber 4, and the tube connection port The three-way switching valve 20 is controlled so that 13 is connected to the compressor 14 via the tube 22. Thereby, filling of the fluid into the plurality of syringes 6 is started.

  According to the fourth embodiment, the fluid 10 is prevented from dripping into the syringe 6 before the inside of the chamber 4 is sufficiently evacuated, and bubbles are prevented from being mixed into the fluid in the syringe 6. Can do. The other points are the same as in the first embodiment. Also in the second or third embodiment, the switching valve 20 or the like may be provided as in the fourth embodiment.
