Description

  The present invention relates to a gel manufacturing apparatus.

As a conventional technique, a method of manufacturing a gel by discharging a discharge liquid by a droplet discharge method toward a liquid to be discharged is known. For example, a discharge port (nozzle) that discharges a discharge object is arranged at a certain interval with respect to a liquid to be discharged in a stationary state, and the discharge object discharged from the nozzle by the droplet discharge method is stationary. A method and apparatus for producing a gel by reacting with a liquid to be ejected in a state is disclosed (for example, see Patent Document 1).

Japanese Patent Laid-Open No. 2001-232178 (pages 3 to 6, FIG. 1) JP 2007-245151 A (pages 3 to 5, FIG. 1)

  However, since the distance (interval) between the ink jet head and the liquid level of the liquid to be discharged is close to 0.1 mm to 1 cm, the discharge target is discharged due to vibration caused by discharge of the discharged material onto the liquid surface of the liquid to be discharged. There is a problem that the liquid level of the liquid shakes, the liquid to be discharged enters the nozzle of the inkjet head, the inside of the nozzle becomes a gel, and discharge failure occurs.

  The present invention has been made to solve at least a part of the above problems. It can be realized by the following forms or application examples.

  [Application Example 1] A gel manufacturing apparatus according to this application example is a gel manufacturing apparatus that generates a gel by reacting a first solvent and a second solvent, and a fluid mechanism that causes the second solvent to flow. A discharge mechanism having a nozzle plate in which a nozzle for discharging the first solvent by a droplet discharge method is formed in the second solvent, and a gap plate in which a through hole communicating with the nozzle is formed. The gist is that the gap plate is disposed between the flow mechanism and the discharge mechanism.

  According to this, since the distance (interval) between the nozzle of the ink jet head and the second solvent flowing through the fluid part of the fluid mechanism is managed by the thickness of the gap plate, the distance (interval) can be easily managed. . Then, the liquid level of the second solvent is shaken by the flow of the second solvent, and the second solvent is prevented from entering the nozzles of the inkjet head from the through hole of the gap plate, and the liquid level is also suppressed. Therefore, it is possible to prevent the nozzles of the inkjet head from being blocked by the second solvent. As a result, the first solvent can be stably discharged from the nozzles of the ink jet head by the droplet discharge method toward the second solvent flowing in the flow portion of the flow mechanism. It becomes possible to stably obtain a gel produced by a chemical reaction with a solvent.

  The gap plate 16 includes a through hole 17 and a groove 18. The gap plate 16 is made of, for example, transparent acrylic. By using the transparent gap plate 16, the alignment between the nozzle 13 and the through hole 17 is facilitated by visual confirmation using a microscope or the like. The through hole 17 and the nozzle 13 are disposed so as to communicate with each other. Accordingly, the first solvent L1 discharged from the nozzle 13 passes through the through hole 17. The through-hole 17 is provided with a water-repellent coating such as fluorine or silicon. Similarly, the gap plate 16 is provided with a water-repellent coating such as fluorine or silicon. The diameter of the through hole 17 on the side facing the nozzle 13 is equal to or larger than the diameter of the nozzle 13. The diameter of the other side of the through hole 17 is equal to or larger than the diameter of the through hole 17 on the side facing the nozzle 13. That is, the through holes 17 have the same diameter or a tapered shape that increases from the side facing the nozzle 13 to the other side. The angle of the taper shape is appropriately determined in the range of 90 degrees to 180 degrees. And the flow part 21 side of the through-hole 17 is processed into R shape.

The gap plate 16 is fixed to a reinforcing plate 19 formed in a frame shape by an adhesive or the like. The mechanical strength of the gap plate 16 is reinforced by the reinforcing plate 19. The outer shapes of the gap plate 16 and the reinforcing plate 19 are formed narrowly from the reinforcing plate 19 to the gap plate 16.
Then, as shown in FIG. 3, the inkjet head 12 is disposed within the frame of the reinforcing plate 19. The inkjet head 12 is fixed by positioning the nozzle 13 and the through-hole 17 by positioning pins 41 and spring pins 42 provided on two opposite sides of the reinforcing plate 19 in a frame shape. For example, four fixed columns 15 are arranged on the reinforcing plate 19. Then, the inkjet head 12 is fixed to the gap plate 16 by a fixing jig 15 a attached to the tip of the fixing column 15. The inkjet head 12 can be attached to and detached from the gap plate 16 by the fixing jig 15a.

  The groove 18 is formed on the gap plate 16 on the inkjet head 12 side. And it connects with the through-hole 17, and as shown, for example in FIG. In a state where the inkjet head 12 is overlaid on the gap plate 16, at least a part of the groove 18 of the gap plate 16 is exposed without being covered by the inkjet head 12. The depth of the groove 18 is about half of the thickness of the gap plate 16. The groove 18 is provided with a fluorine-based water-repellent coating.

The flow mechanism 2 causes the second solvent L2 to flow. Then circulate.
The flow mechanism 2 includes a second tank 20 that stores the second solvent L2, a flow section 21 and a discharge section 22 through which the second solvent L2 flows, and a solvent circulation section 23. The second tank 20 is in communication with the filter 25 and the fluidizing part 21. The discharge part 22 is in communication with the fluid part 21. The second solvent L2 stored in the second tank 20 is filtered by the filter 25 and flows to the fluid part 21 and the discharge part 22. And the discharge part 22 allows the 2nd solvent L2 which flowed through the fluidized part 21, and the produced | generated gel G to pass through. The solvent circulation unit 23 includes a pump 24, for example. The second solvent L2 that has passed through the discharge unit 22 is collected by the solvent circulation unit 23 and circulated to the second tank 20 by the pump 24.

  A head mounting portion 26 is formed in the fluid portion 21. For example, as shown in the drawing, a part of the flow portion 21 is cut in accordance with the shapes of the gap plate 16 and the reinforcing plate 19 to expose the tubular inside of the flow portion 21, thereby making the head attachment portion 26. obtain. Here, as shown in the drawing, since the reinforcing plate 19 is formed thinly from the gap plate 16, the head attachment portion 26 has a tubular interior that is narrower than the tubular exterior of the fluid portion 21. Further, a valve may be disposed between the second tank 20 and the filter 25 or between the filter 25 and the head mounting portion 26 of the fluidizing part 21 to control the flow rate or flow rate to the fluidizing part 21. Good.

  The second tank 20 is made of, for example, transparent or translucent polyethylene. The flow part 21 and the discharge part 22 are made of, for example, transparent acrylic and are formed in a tubular shape. The discharge part 22 is formed in an L shape so that the second solvent L2 flowing from the flow part 21 does not scatter from the discharge part 22.

  The head mounting portion 26 is formed with a seal portion 27 such as waterproof rubber or an O-ring. Then, the gap plate 16 and the reinforcing plate 19 of the discharge mechanism 1 are disposed on the head mounting portion 26, and the second solvent L 2 flowing through the fluid portion 21 is sealed by the seal portion 27 so that it does not flow out from the fluid portion 21. Has been. Further, the seal portion 27 may be fixed to the gap plate 16 and the reinforcing plate 19 of the discharge mechanism 1 with an adhesive or the like.

  By causing the second solvent L2 to flow between the flow portion 21 and the gap plate 16, the inside of the through hole 17 of the gap plate 16 becomes negative pressure, and this is utilized to air from the groove 18 to the through hole 17. Create a (gas) flow. Thereby, it is possible to prevent the second solvent L2 from flowing into the through hole 17 of the gap plate 16 from the flow mechanism 2. Furthermore, the discharge speed of the first solvent L1 discharged from the nozzle 13 of the inkjet head 12 can be maintained or assisted.

  Further, in the ejection mechanism 1, the flow portion 21 side of the through hole 17 is processed into an R shape, so that the second solvent L 2 enters the nozzle 13 of the inkjet head 12 from the through hole 17 of the gap plate 16. This prevents the nozzle 13 from being blocked by the second solvent L2.

In order to define the distance (interval) between the nozzle 13 of the inkjet head 12 and the liquid surface of the second solvent L2 that is flowed by the flow mechanism 2, the thickness of the gap plate 16 is determined. In the present embodiment, the thickness is appropriately determined from 0.1 mm to 10 mm.
The solvent circulation unit 23 collects the second solvent L2 that has flowed through the flow unit 21, the discharge unit 22, and the gel collection mechanism 3 described later, and circulates it to the second tank 20.

The gel collection | recovery mechanism 3 collect | recovers the gel G produced | generated by discharging the 1st solvent L1 to the flowed 2nd solvent L2.
The gel recovery mechanism 3 includes a recovery net 31 and an XY table 32. The collection net 31 is arranged on the XY table 32. The recovery net 31 is moved by moving the XY table 32 so that the gel G that has passed through the discharge part 22 of the flow mechanism 2 does not overlap on the recovery net 31. The mesh of the collection net 31 is less than 100 μm in diameter of the gel G, for example, less than 80 μm. The moving speed of the XY table 32 is set to 1 mm / s or more when the diameter of the gel G is 100 μm and the discharge frequency is 10 Hz, for example.

  The discharge measurement mechanism 4 measures the weight of the first tank 11 of the discharge mechanism 1. By measuring the weight of the first tank 11 containing the first solvent L1, the weight of the first solvent L1 discharged from the nozzle 13 is measured from the weight difference before and after the discharge.

  The gel weighing mechanism 5 includes a laser light source 51 and a photoelectric detector 52. The projection light projected from the laser light source 51 is irradiated to the fluidized part 21 in which the second solvent L2 and the gel G are fluidized. Then, the quantity, shape, and size of the generated gel G are measured by receiving the reflected light from which the projection light is reflected by the photoelectric detector 52 in the flow portion 21.

The observation mechanism 6 observes or measures the state of the gel G recovered by the gel recovery mechanism 3, such as the shape and size.
The observation mechanism 6 includes a camera 61. The state of the generated gel G, for example, the shape and size thereof is observed or measured by imaging the gel G captured by the collection net 31 using the camera 61.

  Therefore, according to this embodiment, in order to manage the distance (interval) between the nozzle 13 of the inkjet head 12 and the second solvent L2 flowing through the flow portion 21 of the flow mechanism 2 by the thickness of the gap plate 16, Distance (interval) management becomes easy. The liquid level of the second solvent L2 is shaken by the flow of the second solvent L2, and the second solvent L2 is prevented from entering the nozzle 13 of the inkjet head 12 from the through hole 17 of the gap plate 16. Since the liquid level is also suppressed, the nozzle 13 of the inkjet head 12 can be prevented from being blocked by the second solvent L2. As a result, the first solvent L1 can be stably discharged from the nozzle 13 of the inkjet head 12 by the droplet discharge method toward the second solvent L2 flowing through the flow portion 21 of the flow mechanism 2. It becomes possible to stably obtain the gel G generated by the chemical reaction between the first solvent L1 and the second solvent L2.

And even if the 1st solvent L1 is continuously discharged by the inkjet head 12 toward the 2nd solvent L2, since the 2nd solvent L2 is flowing through the flow part 21, the 1st solvent L1 and the 2nd solvent The gels G produced by the reaction with L2 can be obtained one by one without overlapping.
In addition, since the second solvent L2 flows through the flow mechanism 2 without being stationary, problems such as contamination of the second solvent L2 and generation of viable bacteria in the second solvent L2 can be avoided. .

  Further, in the ejection mechanism 1, the flow portion 21 side of the through hole 17 is processed into an R shape, so that the second solvent L 2 enters the nozzle 13 of the inkjet head 12 from the through hole 17 of the gap plate 16. This prevents the nozzle 13 from being blocked by the second solvent L2.

(Second Embodiment)
Hereinafter, the second embodiment will be described with reference to FIGS. 4 and 5.
The gel manufacturing apparatus 10 of 2nd Embodiment gives the same code | symbol about the structure similar to 1st Embodiment shown in FIGS. 1-3, and abbreviate | omits description of a structure.
The gel manufacturing apparatus 10 according to the second embodiment is different from the gel manufacturing apparatus 10 according to the first embodiment in that a meandering section 28 is provided between the head mounting section 26 and the discharge section 22 of the fluid section 21. The point is that the meandering portion 28 is provided with a heating portion 29.

  As shown in FIG. 4, in the second embodiment, a meandering portion 28 that is meandering is disposed between the head mounting portion 26 and the discharge portion 22 of the fluidizing portion 21. The meandering portion 28 is made of, for example, transparent heat-resistant glass, and is formed in a tubular shape. Thus, the gel G flowing in the tubular portion of the meandering portion 28 is caused to meander by changing the flow rate of the second solvent L2 and the gel G flowing in the meandering portion 28. Thereby, the gels G or the gel G and the tubular inside of the meandering part 28 collide with each other in the meandering part 28.

  Furthermore, as shown in FIG. 5, a protrusion 28 a may be formed inside the meandering portion 28, thereby causing turbulent flow to the second solvent L 2 and the gel G flowing inside the meandering portion 28. Cause it to occur. And the gel G is made to collide with the projection part 28a by this turbulent flow.

  The heating part 29 is arrange | positioned so that the meandering part 28 may be pinched | interposed. The heating unit 29 is, for example, a hot plate or a heater provided with a heating wire. The heating part 29 heats the fluid part 21, the second solvent L2 and the gel G flowing through the fluid part 21 at 60 ° C. or less. The heating unit 29 may be disposed so as to be wrapped around the meandering portion 28 and wrap around the meandering portion 28.

Therefore, according to the present embodiment, the second solvent L2 and the gel G are meandered inside the tubular portion of the meandering portion 28 by the meandering portion 28 while the same effect as that of the above-described embodiment is achieved. The flow rate of L2 and gel G is changed. Moreover, the flow rate of the 2nd solvent L2 and the gel G is changed by making the gel G collide with the projection part 28a.
In this way, turbulent flow is generated in the second solvent L2 and the gel G flowing inside the tubular portion of the meandering portion 28. For example, even if the surface of the gel G is rough or has protrusions or the like and is not spherical, the turbulent flow causes the gels G or between the gel G and the tubular inside of the meandering portion 28, Alternatively, the gel G is further made into a true sphere by colliding the gel G with the protruding portion 28a. Alternatively, even if a plurality of gels G are attracted in a thread shape and are flowing from the flow part 21, they are separated into a plurality of gels G in the meandering part 28, and then each gel G is Made into a sphere.
Moreover, it can harden quickly by heating the gel G at normal temperature or more and 60 degrees C or less.

(Third embodiment)

The gel manufacturing apparatus 10 according to the third embodiment is different from the gel manufacturing apparatus 10 according to the first or second embodiment in that an ultrasonic wave is provided between the head mounting part 26 and the discharge part 22 of the flow part 21. It is a point provided with generating part 33a, 33b.

  As shown in FIG. 6, the ultrasonic generators 33a and 33b apply different ultrasonic waves to the flowing second solvent L2 and gel G, respectively. One is to generate a low frequency of about 20 kHz from the ultrasonic wave generator 33a. The other one generates a high frequency of several MHz from the ultrasonic wave generator 33b.

According to this, cavitation (bubbles) is generated by adding a low frequency of about 20 kHz to the flowing second solvent L2 and gel G. Thereby, it is suppressed that the produced | generated gels G are attracted | attached or connected to a thread form.
Then, by applying a high frequency of several MHz to the flowing second solvent L2 and gel G, the molecules of the second solvent L2 themselves are vibrated. Accordingly, the generated gels G are restrained from being caught or connected in a string shape, and the gel G is made to be a true sphere.

(Modification)
The gel manufacturing apparatus 10 may be housed in a microwave generator such as a microwave oven.
According to this, both the first solvent L1 and the second solvent L2 are ejected while being vibrated by microwaves, and are vibrated even after the ejection, so that the gels G are attracted or connected in a string form. Can be suppressed.

(Fourth embodiment)
Hereinafter, a fourth embodiment will be described with reference to FIG.
In the gel manufacturing apparatus 10 of the fourth embodiment, the same reference numerals are given to the same configurations as those of the first to third embodiments shown in FIGS. 1 to 6, and the description of the configurations is omitted.
The difference with the gel manufacturing apparatus 10 by 4th Embodiment with respect to the gel manufacturing apparatus 10 by 1st-3rd embodiment is a point provided with the two flow parts 21. FIG.

The fluid part 21 is arranged so as to be shifted from the center of the tubular discharge part 22. The flow directions of the second solvents L2 from the two flow portions 21 are arranged in opposite directions on both sides of the tubular discharge portion 22, that is, one and the other. The second solvent L2 flowing from the two flow parts 21 into the tubular part of the discharge part 22 flows or rotates in the same direction with the center of the tubular discharge part 22 as the flow center in the tubular part of the discharge part 22. Are arranged to be. Here, the two fluidization sections 21 may cause the second solvent L2 to flow from different second tanks 20, but the present invention is not limited to this, and the second solvent L2 from one second tank 20 is not limited thereto. May be distributed to the two fluidized portions 21 to flow. Moreover, the quantity of the flow part 21 is not limited to two pieces, One piece may be sufficient and three or more pieces may be sufficient.

  Accordingly, the second solvent L2 rotates and flows around the direction in which the first solvent L1 is discharged from the nozzle 13 or the center of the tubular discharge portion 22 to generate a spiral. In this way, since the second solvent L2 is restrained from standing or staying and flowing, problems such as contamination of the second solvent L2 and generation of viable bacteria in the second solvent L2 are avoided. be able to.

  The height difference H between the position of the liquid level of the second solvent L2 stored in the second tank 20 detected by the liquid level sensor 40 and the second solvent L2 flowing directly under the nozzle 13 is set to the nozzle of the inkjet head 12. Assuming that the flow rate V of the second solvent L2 flowing directly below 13 is the following relational expression (1): Here, g is a gravitational acceleration.

  When the position of the liquid level detected by the liquid level sensor 40 is lower than the height difference H, a drive signal is transmitted from the liquid level sensor 40 to the pump 24 via the signal line 44, and the pump 24 is driven to circulate the solvent. The second solvent L2 is supplied from the unit 23 into the second tank 20. Further, when the position of the liquid level detected by the liquid level sensor 40 is higher than the height difference H, a stop signal is transmitted from the liquid level sensor 40 to the pump 24 via the signal line 44, and the driving of the pump 24 is stopped. Then, the supply of the second solvent L2 from the solvent circulation unit 23 into the second tank 20 is stopped. In this manner, the flow velocity V of the second solvent L2 that flows immediately below the nozzle 13 of the inkjet head 12 is determined.
