Description

  In the present invention, for example, two or more kinds of liquids capable of forming an adhesive or a covering portion such as silicone resin, acrylic resin, and epoxy resin are applied to an application surface, and the plurality of types are applied on the application surface. The present invention relates to a liquid mixing apparatus that can mix liquids, a discharger that can be used in the liquid mixing apparatus, and an adhesion method that uses the mixed liquid.

  An example of a conventional liquid mixing apparatus is shown in FIG. 5 (see, for example, Patent Document 1). In the liquid mixing apparatus 1 shown in the figure, a main agent tank 2 and an atomizing head 3 are connected by a main agent supply pipe 4, and a main agent pump 5 and a main agent flow meter 6 are provided in the middle of the main agent supply pipe 4. The curing agent tank 7 and the atomizing head 3 are connected by a curing agent supply pipe 8, and a curing agent pump 9 and a curing agent flow meter 10 are provided in the middle of the curing agent supply pipe 8. The number of rotations of the curing agent pump 9 is manually set. The rotation speed of the main agent pump 5 is set so that the ratio of the respective flow rates detected by the main agent flow meter 6 and the curing agent flow meter 10 is maintained at a predetermined flow rate ratio set by the setting switch 11. The feedback control is performed by.

According to this liquid mixing apparatus 1, the main agent A and the curing agent B are previously fed into the atomizing head 3 at a predetermined flow rate ratio (mixing ratio), mixed in the atomizing head 3 by the mixer 3a, and thereafter By discharging the mixed liquid K from the atomizing head 3, it can be applied to an application surface (not shown). The mixed liquid K applied to the application surface is, for example, a polyurethane resin.
JP 7-185409 A

  However, in the conventional liquid mixing apparatus 1 shown in FIG. 5, the main agent A and the curing agent B are previously fed into the atomizing head 3 at a predetermined mixing ratio, and mixed and mixed by the mixer 3a in the atomizing head 3. Since the liquid K is made, for example, when the coating operation is completed or when the coating operation is interrupted, the atomizing head 3 is disassembled and cleaned before the mixed liquid K in the atomizing head 3 is solidified, or atomized. It is necessary to remove the mixed solution K in the head 3.

  And since the liquid mixture K removed from the atomization head 3 is discarded, it becomes useless, and such liquid mixture K of polyurethane or the like is expensive and has a large loss. .

  For example, when the flow rate of the curing agent B increases, the programmable controller 12 increases the rotation speed of the main agent pump 5 so that the main agent flow rate and the curing agent flow rate become a predetermined flow rate ratio. Even if the number of revolutions is increased, the mixing ratio of the mixed liquid K accommodated in the atomizing head 3 cannot be directly changed. Therefore, there is a time delay until the liquid mixture K having a predetermined mixing ratio can be discharged from the atomizing head 3.

  Furthermore, in the conventional liquid mixing apparatus 1, for example, one of the two types of liquids A and B to be mixed includes one of the liquids A, and this powder and the powder are included. When the difference in specific gravity with the liquid B that is not present is relatively large, even when the two types of liquids A and B are mixed in the atomizing head 3, the powder and the liquids A and B cannot be mixed properly. There is. In such a case, an undesired mixed liquid is discharged.

  The present invention has been made in order to solve the above-described problems, and it is not necessary to disassemble and wash each discharger or remove the liquid in the discharger at the end or interruption of work. For example, even if the flow rate of each liquid supplied to each discharger fluctuates, a liquid mixing apparatus that can mix the liquid at a predetermined mixing ratio without causing a time delay, and a discharger that can be used for the liquid mixing device And an adhesion method.

  The discharge device according to the invention of claim 1 is a discharge device capable of opening and closing a discharge port by moving a valve body having an operation magnet by using an attractive force and a repulsive force of the operation magnet. A closing magnet that biases the valve body toward the closed position that closes the discharge port, and an opening electromagnet that overcomes the force of the closing magnet and biases the valve body toward the open position, The operating magnet is covered with a synthetic resin coating portion, and the closing magnet, the opening electromagnet, and the valve body are partitioned by a synthetic resin partition wall and sealed between them. It is characterized by.

  According to the discharge device according to the first aspect of the present invention, for example, when no current is passed through the opening electromagnet, the valve element moves to the closed position by the force generated between the closing magnet and the actuating magnet, and discharges. The exit is closed. In this state, for example, liquid supplied to the discharge machine at a predetermined pressure can be prevented from being discharged from the discharge port. In a state where a current flows through the opening electromagnet, the force generated between the opening electromagnet and the actuating magnet overcomes the force generated between the closing magnet and the actuating magnet, thereby opening the valve body. It moves to the position and the discharge port is opened. In this state, the liquid supplied to the discharger can be discharged from the discharge port.

  Furthermore, the actuating magnet constituting the valve body is covered with a synthetic resin covering portion, and the closing magnet, the opening electromagnet, and the valve body are partitioned by a synthetic resin partition wall portion to seal between the two. Therefore, the liquid passing through the discharge port can be prevented from directly contacting the operating magnet, closing magnet, and opening electromagnet, and each magnet can be prevented from corroding due to contact with the liquid. .

  According to a second aspect of the present invention, there is provided a liquid mixing apparatus including a plurality of dischargers capable of discharging a predetermined amount of different types of liquids, and a predetermined amount of each liquid for each of the plurality of dischargers. And a controller that controls the plurality of ejectors so that the plurality of types of liquid are alternately overlapped and mixed by being sequentially ejected to a predetermined portion on the application surface.

  According to the liquid mixing apparatus of the second aspect, for example, the control unit first causes the first discharger to discharge the liquid A by a predetermined amount to a predetermined portion on the application surface. Then, a predetermined amount of the liquid B is discharged onto the discharge liquid A applied on the application surface to the second discharge machine. As a result, the discharge liquid A and the discharge liquid B can be applied in a state where the discharge liquid A and the discharge liquid B are superimposed on a predetermined portion on the application surface. In this way, the discharge liquid A and the discharge liquid B are alternately and repeatedly discharged, for example, so that a large number of the discharge liquids A and B overlap each other, so that a mixed liquid, for example, an adhesive is formed. It will be in the state apply | coated to the predetermined part. Of course, it is possible to discharge three or more kinds of liquids sequentially on the coating surface and to superimpose and mix these three or more kinds of liquids in order.

  According to a third aspect of the present invention, there is provided the liquid mixing apparatus according to the second aspect of the present invention, wherein each of the plurality of dischargers is the discharger according to the first aspect, and the plurality of types of liquids are adhesives or coating agents. It is characterized by being a main agent and a curing agent.

  According to the liquid mixing apparatus of the third aspect of the present invention, the main agent and the curing agent are respectively applied to the predetermined portions on the application surface and overlapped, whereby an adhesive or a coating agent can be made at the predetermined portions.

  According to a fourth aspect of the present invention, there is provided the liquid mixing apparatus according to the third aspect, wherein the predetermined amount of liquid discharged from each of the plurality of dischargers is 0.02 cc or less, and any of the plurality of dischargers The time during which no liquid is discharged is 10 ms or less.

  According to the liquid mixing apparatus of the invention of claim 4, by setting the predetermined amount of liquid discharged from the discharger to 0.02 cc or less, and the time during which no liquid is discharged from all the dischargers to 10 ms or less, A plurality of overlapping liquids can be sufficiently mixed, and the function as an adhesive or a coating agent can be sufficiently exhibited.

  In the bonding method according to the fifth aspect of the present invention, different types of liquids are sequentially discharged from a plurality of discharge machines in a predetermined amount so as to overlap at predetermined portions on the application surface, and the plurality of types of liquids overlapping each other. Are mixed by being sandwiched between the application surface and the adherend, and the application surface and the adherend are adhered to each other.

  According to the bonding method of the fifth aspect of the present invention, a plurality of types of liquids that overlap at a predetermined portion on the application surface are sandwiched between the application surface and the adherend, thereby sufficiently mixing the plurality of types of overlapping liquids. It can be made.

  According to the discharger according to the present invention, the operating magnet constituting the valve body is covered with the synthetic resin coating portion, and the closing magnet, the opening electromagnet, and the valve body are partitioned by the synthetic resin partition wall portion. Since the gap between the two is sealed, each magnet does not come into contact with the liquid passing through the discharge port, and the metal component of the magnet can be prevented from being mixed into the discharged liquid. As described above, since the metal component can be prevented from being mixed into the liquid, for example, even if the liquid is solidified when it comes into contact with the metal, the liquid can be discharged so as not to solidify. Accordingly, it is possible to eliminate the trouble of disassembling and cleaning the discharger due to the solidification of the liquid.

  According to the liquid mixing apparatus of the present invention, for example, when an adhesive made by mixing a plurality of liquids is applied to a predetermined portion on the application surface, a plurality of liquids are separately provided from a plurality of respective dischargers. Since a plurality of types of liquids are ejected sequentially in a fixed amount and mixed by overlapping at a predetermined portion on the application surface, even if each type of liquid is stored in each dispenser for a long time, The liquid will not solidify. Therefore, it is not necessary to disassemble and clean each discharger or remove the liquid in the discharger as in the prior art when the application work or the like is completed or interrupted. Therefore, for example, it is not necessary to discard an expensive mixed solution, which is economical. Further, when the flow rate of each liquid supplied to each discharge machine fluctuates, for example, the number of times of liquid discharge is changed in accordance with the flow rate fluctuation, so that a predetermined time delay is not caused as in the prior art. Various types of liquids can be mixed at different mixing ratios.

  According to the bonding method according to the present invention, a plurality of types of liquids that overlap at a predetermined portion on the application surface are sandwiched between the application surface and the adherend, thereby sufficiently mixing the plurality of types of overlapping liquids. And the function as an adhesive can be sufficiently exerted.

  Hereinafter, with reference to FIG. 1 to FIG. 3, an embodiment of the ejectors 13 and 14 according to the present invention, a liquid mixing device 15 using the same, and a bonding method used for the liquid mixing device 15 will be described. . As shown in FIG. 1, the liquid mixing device 15 applies, for example, two kinds of liquids such as the main agent A and the curing agent B separately to the predetermined portion 16a on the application surface 16, and the predetermined portion 16a. These two types of main agent A and curing agent B are mixed to form a liquid mixture K and can be solidified. The main agent discharger 13 discharges the main agent A, and the hardener discharger 14 discharges the curing agent B. Since the main agent discharger 13 and the hardener discharger 14 are the same, the main agent discharger 13 will be described and the description of the hardener discharger 14 will be omitted.

  As shown in FIGS. 2A and 2B, the main agent discharger 13 includes a valve body 17, a closing magnet 18, and an opening electromagnet 19. The valve body 17 is formed in a substantially short cylindrical shape, and is used for opening and closing the discharge port 21 formed in the nozzle 20, and includes an operating magnet (permanent magnet) 22. In FIG. 2A, the valve body 17 is accommodated in a short cylindrical sliding chamber 23 movably in the vertical direction. When the valve body 17 is in the lowered position, the discharge port 21 is closed (closed position). ) As shown in FIG. 2B, when the valve body 17 is in the raised position, the discharge port 21 is opened (open position). In addition, the entire outer surface of the actuating magnet 22 of the valve body 17 is covered with a synthetic resin covering portion 24. The upper and lower ends of the operating magnet 22 are formed as magnetic poles. For example, the upper end is an N pole and the lower end is an S pole.

  As shown in FIGS. 2A and 2B, the nozzle 20 has an upper end fastened to the main body 25, and a wall 23 a of the sliding chamber 23 is integrally provided on the main body 25. It has been. An inlet 26 is formed in the peripheral wall of the main body 25, and a main agent supply pipe 27 is connected to the inlet 26. The inflow port 26 and the discharge port 21 communicate with each other at the lower part of the sliding chamber 23.

  The closing magnet 18 is, for example, a permanent magnet having a substantially short cylindrical shape, and is provided in the upper part of the sliding chamber 23 as shown in FIG. 2A, and upper and lower ends are formed as magnetic poles. For example, the upper end is an S pole and the lower end is an N pole. A closing magnetic pole portion 28 is disposed at the lower end portion of the closing magnet 18, and this closing magnetic pole portion 28 acts as an N pole with respect to the valve body 17. As shown in FIG. 2A, the valve body 17 is pressed downward by a repulsive force that acts between the N pole of the closing magnetic pole portion 28 and the N pole of the upper end portion of the actuating magnet 22 of the valve body 17. As a result, the discharge port 21 can be closed. In this state, the main agent A or the curing agent B supplied to the discharge machines 13 and 14 at a predetermined pressure can be prevented from being discharged from the discharge port 21.

  As shown in FIG. 2A, the opening electromagnet 19 is provided so as to surround the valve body 17 and the closing magnet 18, and includes an electromagnet core 19a. The electromagnet core 19a is provided on the closing magnet 18, and an electromagnet coil 19b is wound around the electromagnet core 19a. An annular opening magnetic pole portion 29 is disposed at the lower end of the electromagnet coil 19b.

  As shown in FIG. 2A, the opening magnetic pole portion 29 is disposed at a side position corresponding to the central portion of the closing magnet 18 in a state where the valve body 17 is in the closed position. That is, in the open electromagnet 19, the open magnetic pole portion 29 is magnetized to the N pole in a state where an electric current is passed, and the N pole open magnetic pole portion 29 is the upper end portion of the actuating magnet 22 of the valve body 17. A repulsive force works between the N poles of the magnets and an attractive force works between the S poles of the lower end of the working magnet 22. The repulsive force and attracting force generated by the opening magnetic pole part (opening electromagnet 19) 29 and the actuating magnet 22 overcome the repulsive force generated by the closing magnet 18 and the actuating magnet 22 as shown in FIG. As shown in (b), the valve body 17 is moved to the open position and the discharge port 21 is opened. In this state, the main agent A or the curing agent B supplied to the discharge machine 13 or 14 at a predetermined pressure can be discharged from the discharge port 21.

  Further, in a state where no current is passed through the opening electromagnet 19, the opening magnetic pole portion 29 is not magnetized, so that the valve body 17 returns to the original closed position as shown in FIG.

  2A, the cover 24, the main body 25, the nozzle 20 and the casing of the valve body 17 are made of synthetic resin. The cover 24 of the valve body 17 is made of, for example, polyether ether ketone (PEEK). ) Is made from.

  As shown in FIG. 1, the inlet 27 of the main agent discharge machine 13 is connected to the discharge port 30 a of the main agent pump device 30 via the main agent supply pipe 27. The inlet 30 b of the main agent pump device 30 is connected to the main agent tank 31 via the main agent supply pipe 27. Similarly, the inlet 27 of the curing agent discharger 14 is connected to the outlet 33a of the curing agent pump device 33 via the curing agent supply pipe 32, and the inlet 33b of the curing agent pump device 33 is The hardener tank 34 is connected via a hardener supply pipe 32.

  Further, as shown in FIG. 1, the controller 35 is electrically connected to the opening electromagnets 19 and 19 provided in the main agent and curing agent discharge machines 13 and 14 via connection lines 36a and 36b. The opening electromagnet 19 is operated by an operation signal from the control unit 35. A main agent flow meter 37 and a curing agent flow meter 38 are provided in the middle of the main agent supply pipe 27 and the curing agent supply pipe 32, respectively. The main agent flow meter 37 and the curing agent flow meter 38 are composed of the main agent A and the curing agent 38, respectively. The controller 35 is electrically connected to the controller 35 via connection lines 39a and 39b so that the flow rate signals of the agent B can be output to the controller 35. In addition, each electric motor (for example, servo motor) 41 provided in each pump device 30 and 33 of the main agent and the curing agent is electrically connected to the control unit 35 via connection lines 40a and 40b. The electric motors 41 and 41 are controlled by the control signal from the control unit 35 so as to rotate at an appropriate rotational speed.

  Each of the main agent and curing agent pump devices 30 and 33 includes, for example, a rotary volume type uniaxial eccentric screw pump 42, and the uniaxial eccentric screw pump 42 includes a rotor 42a and a stator 42b. The rotor 42a has a male screw shape and is attached to a stator 42b having a female screw-shaped inner hole. And one end of this rotor 42a is connected with the rotating shaft of the electric motor 41 via the connecting rod 42c.

  According to the liquid mixing apparatus 15 shown in FIG. 1 configured as described above, the main agent and the curing agent pump devices 30 and 33 are respectively stored in the main agent and the curing agent tanks 31 and 34. The curing agent B can be supplied to the corresponding main agent and curing agent discharge machines 13 and 14 through the supply pipes 27 and 32 of the main agent and the curing agent, respectively. Then, each of the main agent and the curing agent discharge machines 13 and 14 may apply the main agent A and the curing agent B to the predetermined portion 16a on the application surface 16 by an appropriate predetermined amount at an appropriate timing and an appropriate time interval. The control unit 35 controls the electric motors 41 and 41 provided in the pump devices 30 and 33 for the main agent and the hardener so as to open the discharge units 13 and 14 for the main agent and the hardener. An actuation signal can be supplied to the electromagnets 19. The discharge ports 21 and 21 of the main agent and curing agent discharge machines 13 and 14 are set so as to face the predetermined portion 16a.

  Next, referring to FIGS. 3A and 3B, an example in which the main agent and the curing agent discharge machines 13 and 14 apply the main agent A and the curing agent B to the predetermined portion 16a on the application surface 16 will be described. I will explain. First, as shown in FIG. 3A, the main agent discharger 13 discharges and applies the main agent A to the predetermined portion 16a on the application surface 16 by a predetermined amount (one drop). Then, the curing agent dispenser 14 ejects and applies a predetermined amount (one drop) of the curing agent B onto the discharge liquid A applied to the predetermined portion 16a. As a result, the discharge liquid A and the discharge liquid B can be applied to the predetermined portion 16a on the application surface 16 in a state of being alternately overlapped. In this way, the discharge liquid A and the discharge liquid B are alternately and repeatedly discharged, and a large number of the discharge liquids A and B are superposed to form a liquid (adhesive) K in which the discharge liquids A and B are mixed. It will be in the state applied to.

  Thereafter, as shown in the enlarged sectional view of FIG. 3B, the mixed liquid (adhesive) K of the main agent A and the curing agent B that overlaps at a predetermined portion 16a on the application surface 16 is applied to the application surface 16 and the adherend. The application surface 16 and the adherend 44 can be bonded to each other by the adhesive K by being sandwiched between the adhesive 44 and the coated surface 16. And since this adhesive K is sandwiched between the coating surface 16 and the adherend 44 and crushed, a large number of overlapping discharge liquids A, B,... Are sufficiently mixed. The function of can be fully exhibited.

  Incidentally, this adhesive is, for example, silicone for potting. The time during which each of the main agent and the curing agent ejectors 13 and 14 ejects one drop of the main agent A and the curing agent B (the time during which the ejection port 21 is open) is, for example, about 4 ms. The time during which the 13 and 14 discharge ports 21 and 21 are simultaneously closed is, for example, about 1 ms. The discharge amount of each drop (predetermined amount) from which the main agent A and the curing agent B are discharged is, for example, about 0.01 cc. Therefore, if the main agent A and the curing agent B are discharged 10 times each (20 times in total), the time for discharging the 20 drops of the main agent A and the curing agent B is about 100 ms, and the total of the 20 drops. The volume is about 0.2 cc.

  However, the discharge amount of one drop (predetermined amount) from which the main agent A and the curing agent B are discharged is preferably about 0.02 cc or less. This is because if it exceeds this, the two liquids may not be sufficiently mixed. The time during which the discharge ports 21 and 21 of both the discharge machines 13 and 14 are simultaneously closed is preferably about 10 ms or less. If this is exceeded, the viscosity of the applied main agent A and curing agent B will increase, and the two liquids may not be sufficiently mixed.

  Next, by using the liquid mixing device 15 shown in FIG. 1, the main agent and the curing agent discharge machines 13 and 14 are disassembled and washed as in the past when the application work of the adhesive K is completed or interrupted. In addition, it will be described that it is not necessary to remove the main agent A and the curing agent B in each of the dischargers 13 and 14. That is, according to the liquid mixing device 15, as shown in FIG. 1, when an adhesive such as silicone made by mixing the main agent A and the curing agent B is applied to the predetermined portion 16a on the application surface 16, 3 (a), the main agent A and the curing agent B are separately discharged in order from the main agent and the curing agent discharge units 13 and 14, respectively, in an appropriate predetermined amount. Since the adhesive (silicone adhesive) K is mixed by being overlapped at a predetermined portion 16a on the coating surface 16, the main agent A or the curing agent B is accommodated in each of the dischargers 13 and 14 for a long time. Even if it is made, the main ingredient A and the hardening | curing agent B do not solidify. Therefore, it is not necessary to disassemble and clean the respective discharge machines 13 and 14 or remove the main agent A or the curing agent B in each of the discharge machines 13 and 14 as in the prior art at the end or interruption of the coating operation.

  Further, according to the main agent and the curing agent discharge machines 13 and 14 shown in FIGS. 2A and 2B, the operating magnet 22 constituting the valve body 17 is covered with the synthetic resin covering portion 24, and Since the closing magnet 18 and the opening electromagnet 19 and the valve body 17 are partitioned by a synthetic resin partition wall 23a and the two are sealed in a liquid-tight manner, the magnets 22, 18, and 19 Without contacting the main agent A or the curing agent B passing through the discharge port 21, it is possible to prevent the metal components of the magnets 22, 18, and 19 from being mixed into the discharged main agent A or the curing agent B. As described above, since the main component A or the curing agent B can be prevented from being mixed with a metal component, for example, even when the main agent A or the curing agent B is solidified when contacting the metal, the main agent A or the curing agent B is It can discharge so that it may not solidify. Therefore, it is possible to reduce the trouble of disassembling and cleaning the discharge machines 13 and 14 due to the solidification of the main agent A or the curing agent B.

  Next, even when the flow rate of the main agent A or the curing agent B supplied to each of the dischargers 13 and 14 shown in FIG. 1 fluctuates, the main agent A has a predetermined mixing ratio without causing a time delay as in the prior art. And that the curing agent B can be mixed.

  For example, if the flow rate of the curing agent B in the curing agent supply pipe 32 has changed for some reason, the control unit 35 does not change the flow rate of the main agent A, for example, and the flow rate ratio between the main agent A and the curing agent B is previously set. The rotation speed of the electric motor 41 of the curing agent pump device 33 is changed so as to be a value set in the control unit 35, and the number of times the curing agent discharger 14 discharges the curing agent B is changed from 10 times, for example. It can be controlled to change to 9 times or from 10 times to 11 times. That is, a correction amount for correcting the rotation speed of the electric motor 41 provided in the curing agent pump device 33 according to the flow rate fluctuation amount of the curing agent B is stored in the storage unit (not shown), and the curing is performed. The number of corrections for the number of times the agent discharger 14 discharges the curing agent B is also stored in the storage unit.

  The controller 35 rotates the electric motor 41 of the main agent pump device 30 so that the flow rate ratio of the main agent A and the hardener B becomes a preset value without changing the flow rate of the hardener B, for example. While changing the speed, it can be controlled to change the number of times the main agent discharger 13 discharges the main agent A.

  However, in the embodiment shown in FIG. 1, the control unit 35 changes the rotation speed of the curing agent pump device 33 based on the flow rate variation of the curing agent B, and the main agent A and the curing applied on the application surface 16. Although the control is performed so that the mixing ratio of the agent B becomes the set value, it may be controlled so that the mixing ratio of the main agent A and the curing agent B becomes the setting value in the configuration shown in FIG. 4 instead. According to the liquid mixing device 45 shown in FIG. 4, the pressure tanks 46 and 47 for the main agent and the curing agent are provided. By adjusting the pressure of the pressure tanks 46 and 47 to the set pressure, The stored main agent A and hardener B are supplied to the main agent and hardener discharge machines 13 and 14 at a predetermined flow rate, respectively. That is, for example, when the pressure of the curing agent pressure tank 47 fluctuates, the control unit 48 reads the pressure signal of the curing agent pressure detector 49 and based on the amount of pressure fluctuation, the curing agent compressor (air compressor). 50 is turned on and off, and can be controlled so that the mixing ratio of the main agent A and the curing agent B applied on the application surface 16 becomes a set value. Of course, when the pressure in the main agent pressure tank 46 fluctuates, the control unit 48 reads the pressure signal from the main agent pressure detector 51 and turns on the main agent compressor (air compressor) 52 based on the pressure fluctuation amount. It can be turned off and controlled so that the mixing ratio of the main agent A and the curing agent B becomes a set value.

  In the above embodiment, as shown in FIG. 2A, the opening electromagnet 19 and its magnetic pole part 29 are arranged around the sliding chamber 23, and the closing magnet 18 and its magnetic pole part 28 are slid. However, instead of this, the closing magnet 18 and its magnetic pole portion 28 are arranged around the sliding chamber 23, and the opening electromagnet 19 and its magnetic pole portion 29 are arranged in the sliding chamber 23. It may be arranged at the top.

  Moreover, in the said embodiment, although the example which made it apply | coat the adhesive K, such as silicone, to the predetermined part 16a on the application surface 16, was demonstrated, it replaced with this adhesive K, for example, a multiple liquid mixing type The coating agent or coating agent can be applied to the predetermined portion 16 a on the application surface 16.

  Furthermore, in the above embodiment, as shown in FIG. 1, two types of liquids of the main agent A and the curing agent B are separately applied to the predetermined portion 16 a on the application surface 16, and the adhesive K is applied on the application surface 16. However, instead of this, three or more kinds of liquids are separately applied to the predetermined portion 16a on the application surface 16, and a mixed liquid such as an adhesive is formed on the application surface 16. Also good.

  And in the said embodiment, as shown to Fig.3 (a), although main agent A and the hardening | curing agent B were alternately apply | coated on the coating surface 16 drop by drop, it replaces with this and the main agent A and hardening | curing are carried out. For example, when the mixing ratio of the agent B is 1: 2, (main agent A), (curing agent B), (curing agent B), (main agent A), (curing agent B), (curing agent B),. The main agent A and the curing agent B may be applied onto the application surface 16 by discharging in the order of.

  Moreover, in the said embodiment, what contains the granular material in one side among the main ingredient A and the hardening | curing agent B can be used, for example. For example, even when the main agent A contains a powder and a specific gravity difference between the powder and the curing agent B is relatively large, the main agent A containing the powder and the curing agent B are separately applied to the coating surface 16. Since it can apply | coat and mix on top, a granular material can be fully mixed with the main ingredient A and the hardening | curing agent B on the application surface 16 by a suitable mixing ratio.

  Further, in the above embodiment, as shown in FIG. 1, the flow rate of the curing agent B passing through the curing agent supply pipe 32 is detected, and the rotation speed of the electric motor 41 of the curing agent pump device 33 is determined based on the flow fluctuation. However, instead of this, the pressure of the curing agent B passing through the curing agent supply pipe 32 may be detected, and the rotation speed of the electric motor 41 of the curing agent pump device 33 may be adjusted based on the pressure fluctuation. .

  As described above, the liquid mixing apparatus according to the present invention, the discharger and the bonding method that can be used in the liquid mixing apparatus, disassemble and clean each discharger or remove the liquid in the discharger when the work is completed or interrupted. In addition, even if the flow rate of each liquid supplied to each discharger fluctuates, for example, the liquid can be mixed at a predetermined mixing ratio without causing a time delay. It is suitable for application to such a liquid mixing apparatus, a discharger and an adhesion method that can be used for the liquid mixing apparatus.
