Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a droplet discharge device and method for scattering and discharging a liquid material in a droplet state. The term "liquid material" as used in this specification refers to a liquid material, and all fluids are subject to δ. For example, a liquid material having a granular fine substance generally referred to as a filler (f i 1 1 er) is of course covered. In addition, the "liquid droplet state" refers to a state in which the liquid material discharged from the discharge port moves in the space when it is not in contact with the discharge port and the object to be coated. [Prior Art]

A conventional (4) discharge device that ejects a liquid material onto a workpiece after it has left the nozzle, such as: disposed near the outlet to which the nozzle is connected, and is disposed in a non-contact manner with the side of the plunger rod, by means of a plunger : Spray: =) The tip is moved toward the sley and abuts against the valve seat, whereby the liquid material is discharged from the liquid droplets in the state of the liquid droplets (Patent Document 1). In the case where the plunger that does not make the rapid advancement abuts against the valve seat, the technique of "the liquid material is scattered and dripped" is as proposed by the applicant: The liquid material discharge plunger for reading the liquid material advances at a high speed Then, the sputum plunger drive means is stopped in a hurry, and the liquid material discharge method and apparatus discharged from the patent document patent document (Patent Document 2, f3) force the liquid material patent document 1 ·· Japan special (4) table 2G (H_5G (Patent No. 962, Japanese Patent Laid-Open No. 2003-1 90871, Japanese Patent Laid-Open No. Hei No. 2005-296700 No. 97108004 5 200918229 SUMMARY OF THE INVENTION PROBLEMS TO BE SOLVED BY THE INVENTION In the conventional liquid droplet discharge device disclosed in Patent Document 1 in which the valve seat is disposed and discharged, if the plunger rod and the seat are repeatedly contacted, the plunger rod and the valve seat are worn to generate a wear-resistant powder and a wear sheet. When the generated frictional powder and the wearing sheet are mixed into the liquid material, not only the contaminated liquid material but also the liquid material is sandwiched between the plunger rod and the valve seat, which causes a problem of hindering the discharge. Further, because of the plunger rod or Seat wear will change The shape of the plug stem and the valve seat itself will result in reproducibility of the discharge before and after the wear and tear, and therefore the plunger rod and the valve seat must be periodically replaced. Further, when the liquid material containing the fine particles of the filler is called, the liquid material is discharged. At the same time, the filler will be caught between the plunger rod and the valve seat and collapse, and the problem of the change of the liquid material due to the collapsed filler will occur. In addition, the filler which is deformed and deformed will also be It becomes a problem that the nozzle is blocked. c. Furthermore, if the filler is sandwiched between the plunger rod and the valve seat, the contact state between the plunger rod and the valve seat will change each time it is discharged, not only will it be discharged. It is impossible to obtain reproducibility' and there will be a problem that the liquid material does not leave the nozzle, or the liquid material may be scattered, causing the liquid material to adhere to the non-perfect position on the workpiece to contaminate the workpiece. In recent years, it will contain The demand for the solder paste of the solder particles to be discharged in the state of the droplets is increasing, and in order to discharge the liquid material doped with the filler in the state of the droplets, the above-mentioned problem is more important. Patent Documents 2 and 3 Documented The method and the device are all aimed at the weight of 97108004 6 200918229. The plunger is discharged sideways in the liquid chamber. That is, the "into the structure, and the metering liquid advances, so it is quite close to the side of the liquid chamber." Sliding on one side, the opposite: Γ: The amount of liquid material will be discharged with high precision. The interior of the liquid chamber enters the end because the side of the plunger is in contact with limit limits. ~ Sliding resistance causes high-speed movement of the plunger When the discharge operation is performed, the front end of the plunger will not be connected and lifted; the droplet discharge is called special purpose ^ Good discharge =: Placement::: The liquid material of the filler can still be implemented (the means to solve the problem) The first solution means the discharge of the liquid droplet discharge, the chamber; the communication chamber 4: = middle and the front end portion of the plunger is positioned in the liquid chamber to move forward and backward, and the plunger positioning mechanism; The plunger is placed in a non-contact state: set by f, wherein the above-mentioned plunger positioning mechanism is configured to be in the vicinity of the liquid chamber wall in the direction in which it enters and exits. Because the front end of the plunger does not abut against the inner wall of the liquid chamber (corresponding to the case of the f seat L), the liquid material is discharged in a liquid droplet state, thereby preventing the wear of the column base and the valve seat from occurring. The occurrence of the wear and tear piece will prevent the shape deformation caused by the wear of the plunger and the valve seat. The 97108004 7 200918229 can solve the threshold of clamping the plunger rod valve seat without the discharge reproducibility: 砀In addition, the 'filler does not dry between the valve cliffs and collapses. The second end of the plunger and the inner wall of the liquid chamber are discharged in a non-contact state, and the mouth is the side of the plunger. The mouth & /, does not have sliding resistance, so it can reach the effect that J will move the column base at a speed. The 2nd f solution means the first solution means, the above-mentioned plunger that enters and stops t will be Located in the liquid chamber wall and discharge port in the direction of its entry and exit.

That is, by the entry and exit of the child, the front end of the plunger is located near the discharge port, and the liquid resistance of the liquid material moving toward the discharge port due to the plunger action is reduced, and the liquid droplet state is easily generated. It is also effective that the liquid chamber not only forms a spider shape as shown in Fig. 2 but also forms a cylindrical shape as shown in Fig. 8. A third means for solving the first or second means is that the inner wall of the front j-th portion of the liquid chamber is formed in a conical shape having a discharge port at the foremost end. The fourth solution is that in the second or second solution, the inner wall of the front end portion of the liquid chamber constitutes a plane on which the discharge port is provided.

The advance and retreat can adjust the stop position when entering and leaving. By moving the position of the front stop before the discharge, the stop position at the time of the plunger rod in and out can be changed. Therefore, the optimum plunger stop can be set in accordance with the content ratio of the liquid material and the size of the filler. In addition, even if the liquid material and other discharge conditions change, the condition can be adjusted to adjust the plunger to stop at the optimal position, so that it can be discharged well.

The first embodiment described later is based on this method. After the second step of advancing the plunger to bring the front end position to the contact position, the plunger is moved back to the state according to physical characteristics, and the front stopper is retracted and is in a normal state, and then, after the restriction of the plunger retreating movement is released, , then let the front stop the distance required to advance and retreat. The fourth embodiment described later is based on this method. Third, the plunger will use the elastic body to give the elastic force in the direction of the entry and exit. When the structure is in the shape of the liquid chamber (4) at the front end of the structure, the front end is blocked from entering and exiting to the benefit limit. At the clearing point, the branch is advanced and the front end position is set as the contact position, by letting the squad stop and retreat to the distance required to sneak out from the discharge port by making the front abutment portion forward and forward.

(4) Formula (4) sPenser) 3, and a liquid material for the internal discharge of the liquid droplet discharge container 5' is connected to the liquid supply tube at the lower end thereof = the liquid material contains solder particles. Connect the air tube 4, #,έ s. The upper end of the liquid material storage container 5 is supplied with a pneumatic batching machine gas = the air supply port of the batching machine 3. The second control unit 2 is connected to the supply valve 72 when the air that has been pressured and the pressure is set to be changed. , ° 疋〇卩 ,, and also connected to the electromagnetic switch ', the above structure, when, ^ ^ can be in the air tube 4, liquid sputum: "degree of influence" also 97108004 liquid storage container 5, liquid The required position of the chamber 14, the liquid material supply flow path 21, 200918229 17, etc., is set to control the "action" control-temperature control device of the Shanghai 厣 。. The operation of the device of this embodiment will be described. [5] Plunger 40 stop position The setting 3 (4) will be described. First, the electromagnetic other piston chamber 62 is connected to the outside, and the knife is changed to the state in which the movable member 30 is moved to the foremost position. The twist (four) button 32 is moved to the outside because the front piston chamber 62 faces outward. Opened, the action of 66 causes the piston 44 to abut the front striker 51 with respect to the body=coil spring abutting portion 43 and stop;; move: the rear front instrument (9) to advance the rear (four), by contact; Two: The plunger 40 is fixed to the main body 71. After the missing, the ^ is abutted. The H5' is rotated, and it is convenient to fix it by a not-shown: the micrometer 69 does not have another, the edge ring ... "the lock member is fixed. For the Butian coil, the 66 full-flexible micrometer 69 is fixed, and there is still It is possible to hold the contact state even if it is not connected to the first 51. In addition, it can be connected to the fixing member other than the other side, and is configured as the front abutting portion. ^Micrometer 69 12嶋: The piston "cannot move backwards" The structure of the right side of the fixed screw 54 Α, 54β is released, so that the member 27 is moved forward and backward, so that the 单元 7 is opposite to the pedestal, the drive unit 7 〇 uses the self weight to face forward The status below is manually moved). Here, since the rear convex portion 4^ can also be formed to have substantially the same inner diameter, the drive unit 70 does not generate vibration when the cover is searched for and the sliding concave portion is moved. 7G moves forward 97108004 22 200918229 because The driving unit 70 is fixed in a state in which the rear stopper 52 is in contact with the rear abutting portion. Therefore, when the front end 13 of the plunger rod 41 reaches the contact position 12 of the inner wall of the contact liquid chamber 14, the downward movement is formed. The state in which the plunger 40 is restricted. This state is referred to as "standard state". Further, in a specification state in which the front end 13 of the plunger rod 41 is in the contact position 2 and the rear abutment portion 45 abuts against the rear broadcast 52, the fixing screws..., 54B are locked, and the body 71 is fixed to the base member. 27 on. Further, the moving member 30 is located at the forefront, and a state in which a gap occurs is formed in front of the body 71 and behind the knob 32. The following description will be made with reference to Fig. 3(b). When the rotation button 32 is rotated in the right direction, only the movement #3〇 is moved: the second concave portion 22 of the discharge block 81 fixed to the base member 27 and the square convex portion 31' are screwed by screws. The sliding μ and the rear convex portion 3 3 are slidable. If you continue to turn the knob 32 to the right (four), finally, the rotation will connect (4) the front of the body 71. Since the body 71 is fixed to the base member 27 by the solid (four) 54B, the ^^^ which is in contact with the rear of the wire, and the too-n button 32 cannot be further rotated. Moving member 3〇: This value is memorized when the specification state is set to the stop position at the time of entry and exit, and the 1st table is not Sq'. The following description will be made with reference to Fig. 4(C). 54A ' 54B 5 32 ^ Slide the front end surface of the main body 71 on one side, and press the side to the side. Since the main body?! is in a state in which the forward movement 97108004 23 200918229 can be performed, "the movement of the moving member 3 body 71 (4) is used to move back". This is the value s when the position is stopped at the time of entry and exit. The distance between the specification state terminal 13 and the contact position 12. The front body 71 can be correctly moved to the rear, and the front abutment portion 43 in the state of 51 is used to contact the front stop. The front end 13 of the plunger rod 41 is moved rearward by the second and second plugs, and J1 d is separated from the contact position 12. When the memory 29 is confirmed, if it is moved backward: the rotation of the rotary button 32 is stopped. Excessively toward the rear: two rotations will rotate the rotation button 32 in the opposite direction to adjust. Since the position of the tampering member 30 becomes the plunger, it stops when entering and exiting = memory. In addition, the better of the plunger 4. It is preferable to perform the test in advance and obtain the test. ▲According to the above operation, the stop position of the plunger 4〇 can be adjusted, and the front end 13 of the plunger rod 41 is not in contact with the contact position. If the plunger 40 enters and exits the stop position When the adjustment has been completed, the fixing screws 54A, 54B are locked, and the driving unit 7A is fixed to the base member. Moreover, the fixing screw for fixing the rotation of the rotary knob 32 can be locked. μ is described below with reference to Fig. 4(d). The micrometer 69 is rotated to retract the rear stopper 52, and the amount of movement when the plunger 40 is retracted at the time of discharge is determined. Then, in order to prevent the micrometer 69 from rotating, it is convenient to fix the micrometer 69 by a rotary lock member such as a fixing screw 97108004 24 200918229 (not shown). According to the above operation, the stop position setting operation of the plunger 40 is performed. After the second and subsequent operations 'after setting to the canonical state, the body (ie, the front load 51) is turned rearward by the use of the moving member: part ^), so that the plunger 4G can be stopped at the time of entry and exit. ;= The same position is owed. Therefore, by performing the test first, and remembering the stop position when the plunger 40 that is well discharged is in and out, the setting operation can be performed even after the unknown test. Other factors that have not been controlled have changed. The stop position of the column base 4G is better: the following: the same setting will not be able to obtain a good discharge.: It will be necessary to perform the test, even in this case, by stopping the entry and exit of the columns. The position starts from the last position, then the time it takes to test. Because the environment changes: j big change =: when the plunger 4° better in the exit position does not replace the memory with the = 29, instead of using a display device such as a liquid crystal, a value indicating the position of the moving member 30 is displayed. The value of the position at the time of production is set to display zero, and the discharge of [6] is removed from the contact position 12. Good back distance. 1) Setting before discharge operation: ==3 The pressure of the air supplied to the front piston chamber 62 against the pressure of the coil spring 66 moving the piston 44 backward. 97108004 25 200918229 Force. From 3 =: 3 pairs of liquid material storage capacity "the pressure of the supplied air is matched with the required force of the liquid supply chamber 14. From the pneumatic (time series), it is set so as not to cause liquid vapor leakage from the discharge port 10 described later. 2) The standby state before the discharge operation is as follows, refer to Fig. 5(e). The f chamber === electromagnetic switching chamber 72, and the front piston side is in the second state (that is, the atmosphere is open). In the state of the plug-in, it is convenient to use the coil to praise the live 51 2: and set the front abutting portion to complete the adjustment of the position of the front stop 51, and the interval between the end 13 and the liquid chamber 14 can be separated. == the required interval between the contact positions U. The liquid chamber 14 will be formed in a state filled by the liquid material before the second: coffin. This case is in accordance with the liquid material outlet 1G of the plunger rod 41. In the state, the air is supplied to the material storage tank 5 by the pneumatic batching machine 3, and is carried out through the middle of the tube. The U liquid supply official 6 reaches the liquid chamber = the machine state, and the pneumatic batching machine 3 is not implemented. The liquid is supplied with air. That is, the transfer of the liquid material in the liquid material storage container 5 will be stopped. ^ There is a gap between the front end 13 of the plug 41 and the contact position u in the liquid chamber 14, and the liquid material still does not leak from the discharge port (4) of the nozzle η. Here, there is 97108004 26 200918229 = ί, the supply of pressurized air, It will still be caused by the self-weight of the liquid material, and the liquid material will be entangled from the liquid chamber 14 from the +, Β 13 13, 盥, 夜 宫, 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋The gap is very large [therefore, the situation is caused by the self-weight and the leaking of the i. However, the ## can be used in the nozzle=5 according to the possibility of using the pneumatic ingredients (4) in accordance with the uncontrolled various conditions. The air is exhausted. 3) The U is leaking. In the following, referring to Fig. 5(f): The foot control unit transmits a signal to the electromagnetic switching valve 72, and the air supply source Μ is empty: the flow path 48 becomes The front piston chamber 62 is connected to the right, and the air is supplied from the gas supply source 73 to the front to supply the supplied air. The piston 44 will contract toward the soil (10) and the piston 44 will push backwards. The batching machine 3 supplies air, and the liquid is pneumatically used, if by living Then the state is the same. That is, the liquid chamber 14 is originally retracted by the plunger sample 41, and the vertical will occur from the discharge ... into the air:: the second inside will not be shaped, and the retreat of the plunger 40 will be rearward. It is limited to 52, and this situation is as described in the following. In addition, in this embodiment, air pressurization is performed in the thin 5 during the discharge operation, and the second * is referred to below for the liquid storage container. Fig. 5 (g). 97108004 27 200918229 攸 control 邛 transmits the ## to the electromagnetic switching valve 72 to form the front piston chamber 62 in a state of being in communication with the outside. If the front piston chamber is open to the atmosphere, the coil spring is conveniently used. 66 presses the piston, the plunger 4 will be slammed toward the front, and 43 will be abutted in the silk chamber 61 μ j ^ piston 44 (four) square abutment. ^ ^ 挡 挡 5 丨, then slammed The plunger 40 moves toward the other side. Only the guest guest}圼/,,, the inner wall stops before the Ή^ terminal 13 is also just about to abut the liquid chamber '=4〇 forward will be in front of the front end 13 of the plunger rod 41, the second sex force. The front end 13 of the plunger rod 41 will be given as described above, the liquid plunger rod 41 is opposite to the liquid material at this time, because the plunger rod 41:::=droplet 嶋^ thus there is no need to worry about the liquid chamber The inside of 14 is connected to the liquid chamber 14, and the agent will adversely affect the discharge. The plunger contained in the material in the time is filled with the plunger: row: 'It is better to advance and stop in and out of the second I;: the end 13 and the inner wall of the liquid chamber 14 are filled::: Nine In the front of 4!, it can be as close as possible.

According to the apparatus of the present embodiment, the plunger 4 is made. Litian stops 51 and stops. Therefore, even if the plunger 4 J that moves at a high speed stops at a rapid stop position, the liquid material can be sufficiently positively fixed. [Example 2] After starting the discharge operation, the liquid is often started. Air is applied internally, but the apparatus of this embodiment is in the opening. After the discharge, the air supply to the liquid storage container 5 is also stopped. That is, the present embodiment is a device of the embodiment ,, and the control of the liquid material passing through the front end 13 of the plunger rod 41 and the liquid chamber 14 = continuous leakage from the discharge port 10 is continued. (4) Discharge (4) 'Times with reference to Fig. 6 and Fig. 7U) Fig. 6 is not a substrate on which an object to be coated indicating the discharge position is attached. In the figure, the position is discharged from (i to (1 V) point system & the discharge device is moved at a constant speed toward the head of the figure, and is moved without stopping even during discharge. The movement can be performed by the substrate and Any one of the discharge devices moves. Fig. 7(a) shows a timing chart of the operation of the plunger rod 41, the pressurized state of the pneumatic batching machine 3, and the state of the electromagnetic switching port 72. Fig. 7(a) The pattern of the electromagnetic switching valve 72 is such that the state of the center of the front piston chamber 62 is "(10)", and the phase of the front piston chamber (10) is "GFF". The pattern of the pneumatic batching machine 3 is applied. The state of the pressurization gas supply is set to "0N." Since the respective discharge positions of the plunger rod 41 are advanced and discharged as shown in Fig. 6, the column base rod 41 must be retracted in front of the discharge position. 97108004 29 200918229 : Self-exit: When the two are close to the discharge position (1) shown in Figure 6, the signal of time urination 桂 捍 Γ Γ ? ? ? ? 电磁 电磁 电磁 电磁 电磁 电磁 电磁 电磁 电磁 电磁 电磁 电磁 电磁 电磁 电磁 电磁 电磁 电磁 电磁 电磁 电磁 电磁 电磁 电磁 电磁 电磁 电磁 电磁 电磁 电磁The signal of the ministry, Pneumatic 3 will become a Γ〇Ν", for the storage of liquid milk, ^ The liquid supply is started to be supplied to the liquid chamber. The retreat of the inner 7 and the paper rods 41 is before the discharge port 1 is reached to the discharge position (1), and when the discharge position is reached by (1), the column is used. Plug rod: =.

The discharge is reached and the r is reversed toward the discharge position (6). The period from when the plunger function 41 starts to retreat is started, that is, during the backward direction movement, the column coffee chamber discharge port 1〇. In the cough plunger cup 41 The front end 13 is not supplied in the plugging container 5: the two-gas de-energizing batching machine 3 does not store the liquid material and does not leak liquid from the discharge port: the liquid material is supplied in the liquid chamber 14, due to the time c The operation operation during the period of e-e. That is, the operation at the same position (out) during the discharge position [. during the period a to C is performed after the discharge is performed, and then moved to the discharge position (moving discharge position).

When the discharge port 10 is close to the discharge position (1), the signal of the coffee department will be electromagnetically switched to the valve) = between e), and the convenience will be used for 41 to retreat. The knife is changed to 0N", and the plunger rod batching machine 3 becomes Γ0Ν", and the signal of the second part is 'pneumatic gas, and the liquid chamber 14 is supplied with the liquid material w. The convenience of the discharge position ((1)) is from the control unit's setting (out) (time f),

",", the two strokes have been completed: ::: 72 is switched to because the discharge is performed at the discharge position (1) i) A discharge position (iv), so that the air must be pressurized immediately after the discharge. That is, the pneumatic two-action batching machine 3 will continue to supply the advancement of the plunger rod 41 so that #=3 will maintain the "(10)" state " discharged by the droplet state to the discharge position (::; The liquid material is at the discharge position of the forward movement 6 (5) of the plunger rod 41, and is formed as follows: after the door is formed, the row 1: port 1 will be located close to the second and the second block will be switched to "(10)". The plunger rod 41 is executed = the liquid material supply in the chamber u will remain in the 〇N" state, so that the retreat is tied to the time before the discharge ° 1G reaches the discharge position (iv), and then the second time reaches the discharge position (1V). (That is, the time is from the old department of the control department, and 0R* +Tf is "〇FF", then the second two that have completed the retreat will advance. 72 switch 97108004 200918229 a 2 after reaching the discharge position (lv) Immediately, the discharge is performed, and the emulsifiable batching machine 3 is set to "_", and the internal co-reception is stopped. By the advancement of the plunger rod 41, the liquid material is discharged from the discharge state by the discharge port 10 Position (5) = Example by using the plunger rod between the discharge and discharge ^ will stop using the pneumatic batching machine 3 to the liquid material storage container 5 = The twisting of the air supply and the supply of the liquid material in the liquid chamber 停止 are stopped, and the leakage of the liquid material from the gap of the discharge port 10 can be prevented. ^ Again, as at the discharge positions (iii) and (iv) When the discharge period is closer, because the row J beam from the discharge position (1) i): :: the discharge position (lv) is discharged for a shorter period of dry stop period - almost never occurs from the discharge port ίο lx liquid In the case of leakage of material, if the storage of the liquid material is not stopped, the use of the pneumatic batching machine to store the pressurized air supply, there will be no problem in the discharge. The interval between the discharge and the discharge will be short. Will affect the displacement pressure II from the discharge position (1) toward ((1) movement, stop the supply of pressurized air. τ Shigong also badly stop using the pneumatic batching machine 3 to perform = two!? and stop the liquid chamber The supply of liquid material in 14 will not cause liquid leakage in the outlet port 10. The supply time of the pressurized air is suitable for the ® ^ compounding machine 3, because it will vary depending on the liquid material, discharge conditions, etc. Therefore, the test will be carried out before the discharge begins. 97108004 32 200918229 Calculate and determine the appropriate time and set. Here, the stop sequence can be stopped before the plunger rod 41 starts to advance, == ^:. 41 stops after the completion of the advancement. In the embodiment, the time to be performed by the pneumatic batching machine 3 is controlled by the pneumatic batching machine 3, and the control is performed. The signal is transmitted to stop the supply of the pressurized air. [Embodiment 3] The pneumatic batching machine 3 performs air supply, and the time until the liquid material is transferred to the inside of the liquid, and the time until the switching two:: two air supply source 73 communicates with the front piston chamber 62, and the time until the dry back is retracted There will be deviations in the situation. Fig. 7(b) shows the time until the liquid material is transferred into the liquid chamber 14 by the use of the pneumatic batching machine, = switching the electromagnetic switching valve 72, and supplying the air to the end, and the column is connected.

The other action of the 'plunger rod 41 is installed, the disk is opened to the ^ - A η ^ ^ ^ ” to start the supply of the liquid to the liquid 14 , and is also Γ , and can also be set in the range of good discharge. [Embodiment 4] As shown in Fig. 8, the apparatus of the κ embodiment is such that the rear portion 33 of the moving member % directly abuts against the front abutting portion 43, and the body 71 belongs to a structure that does not move. 71 will be fixed to the base member 27, and will be moved forward and backward. The forward convex portion 31 of the moving member 30 will be screwed into the rear concave portion 22 of the discharge block 81. The rear convex portion 33 is slidable. Inserted into the sliding hole of the body?! The rear end surface of the rear convex portion 33 will constitute a front stop to reach the front piston chamber 62. The inner peripheral surface of the sliding hole 25 is provided with a ring 97108004 34 200918229 groove, and An annular on seal 18D will be provided in the groove. The seal 18D will be in close contact with the moving member 30, because the moving member will still maintain the close contact state, so that the gap is lost to the outside when the living body moves." ^ will not pass through the central axis of the moving member 30. Because the through hole 3 4 (4) The through hole κ 仫4 of the plug 4G is inserted into the outer diameter of the connecting portion 42, and the column groove vibrates in S. The inner peripheral surface of the through hole 34 is provided with an annular ring-shaped annular seal 18 Ε. 18Ε will be in close contact with the two ports. Even if the plunger 40 is in close contact with Jiang Xukan, the gap will leak out to the outside when the member 3 moves forward and backward. The air plugged into 61 will not pass. When rotating in the right direction, the front stop 51 moves toward the contact position 。 toward the rear. If the rotary button shirt 1 W 19 ^ 2 rotates in the reverse direction, the moving member 30 稷 稷 稷 位置 位置 位置 位置 蒋 蒋 ± ± 1. Move. On the surface of the birthday button 32, the memory 29 will be set as in the example 1. 1 In front of the discharge block 81 # 01 # & 11 Neiqiu j square recess 21 will be embedded in the nozzle 11 The cylindrical space 形成 formed in the nozzle door 4 is larger than the liquid chamber 14. The liquid chamber 14 is a space having a diameter ◦ I, and a discharge port W is provided at the center of the front. The first 14 ιλι ^ αλ / advances in and out movement, and the position abutting on the inner wall of the liquid chamber 14 becomes the contact position i 12 = the front end 13 blocks the row The exit bell forms a state at one end of the splitting outlet 10 at the contact position 12. The column of the apparatus of the present embodiment will be described. The material 41 is in the order of the Weiding, and the moving member 3 is moved as far as possible to the side, and The front stop 51 97108004 35 200918229 The position of the moon 丨J into 0 such a field, & 丄 & Because the plunger 40 will use the coil magazine 筈 μ to give the forward force, thus the test & brother + n ^ u It will move forward with the block stop 51. Then, if the rotary knob 32 is turned to the left &#丝二+ + ^ and the universal twist, the plunger 40 moves forward, and the front end of the plunger rod 41 rides * and the liquid contacts the liquid The inner wall of the chamber 14 (reaching the contact position 12) will not move further because the plunger 4 will move forward, and only the moving member 30 will move toward the side. After the narrowness m ",, the rear side stop 51 and the front abutment portion 43 become untouched. Manipulating the micrometer 6 9 and #德古# c:. moving the rear stop 52 forward, by making the rear The abutting portion 45 abuts against the rear suspension-stop 52 to restrict the backward movement of the plunger 40. Whether the rear abutting portion 45 is right-handed and has been abutted to the rear stop 52, Taking the micrometer 6 9 has the effect that the silk is broken like a gentleman. ..., the state of the moving movement of the target is determined, and the retracting movement of the column 40 is determined to be restricted, and the rotating member is moved. 3. Moving toward the rear, ===::Moving::: Whether the 51 has abutted against the front and easily judges that the moving member 30 can no longer move backwards. 1:1 or more = 乍 方 3 The front end 13 of the rod 41 is in contact with the liquid chamber state. The value of the device (10) that contacts the front read 51 is entered; By operating the micrometer 69 in the state of the normal state, the rear stop (4) of I: the rear abutment portion 45 is formed, and the plunger-to-heart 97108004 36 200918229 can be moved, and the member 3G is moved rearward. Whoever moves the front abutting portion 43 toward the rear. By column A. If the value of the memory 29 is compared, the value of the memory 29 can be accurately grasped. If you confirm the value of ^ while moving only the required distance to the rear, the rotation will stop. When moving excessively toward the rear, the rotating man is rotated in the opposite direction. In this case, the entry and exit of the plunger rod 41 can be stopped at a desired position where the front end 13 of the plunger rod 41# does not come into contact with the contact position 12. The longitudinal micrometer 69 is used to retract the rear broadcast 52 and determine the amount of movement of the plunger 40 after the discharge. If the amount of rearward movement of the plunger 4 is determined, in order to prevent the micrometer 69 from rotating, it is convenient to fix the micrometer 69 by a lock member such as a fixing screw (not shown). By the above operation, the retracted position of the plunger 4 is adjusted. The apparatus of this embodiment differs from the apparatus of the embodiment 就 in the shape of the tip end 13 of the nozzle 11 and the plunger rod 41, and the configuration of the liquid supply flow path 17. In the apparatus of the first embodiment, the inner wall of the nozzle 1 is oriented toward the discharge port 1 and the inner surface is formed in a mortar shape. The apparatus of the present embodiment forms a narrow hole on the side of the discharge port 丨0 and is connected to the side of the liquid chamber 14 side. The shape of the diameter hole, and the connecting portion forms a right angle surface with respect to the front and rear direction. Further, the front end 13 of the plunger rod 41 of the apparatus of the present embodiment is flat. Further, the apparatus of the present embodiment does not use the liquid supply tube 6, but connects the liquid material storage container supply flow path 17 by the flow path provided in the liquid material supply member 8 in the hard 97108004 37 200918229 5 . The discharge operation is also the same as that of the apparatus of the first embodiment, and the apparatus of the first embodiment is the same. Γ = The construction of the member 30 is not limited to the embodiment and the embodiment! The configuration I can adjust the distance between the front load 51 and the contact position: 12; preferably; when the front stop 51 is moved forward, the front end will be touched by ^12: while the front load 51 will leave. The shape I of the front abutting portion 43. In addition, it is preferable to form the front end 13 to reach the contact position Μ, and the state of abutting against the front abutting portion can be performed from the outside. [Example 5] The system is modified as shown in FIG. 9 instead of the pneumatic batching machine 3, The liquid supply device is constituted by the system 7. The pump 7 is disposed in the middle of the liquid supply pipe 6 that connects the liquid material storage flow path 17. The (4) (4) system of the fruit 7 is mainly composed of a tube pump 7, a meter, a go & / ^ piston pump, which is used to feed the liquid material into the tube by means of a roller. The ten-mile piston 44 and the switching valve are configured to operate the pump 7 to discharge the liquid material into the liquid chamber 14. Other Related Structures In the apparatus of this embodiment, the liquid material in the storage container 5 is transferred as in the apparatus of the first embodiment. Cooperating with the column base 40, the apparatus of the present embodiment is preferably controlled as in the movement of the embodiment 2 and the pump 7. [Embodiment 6] 97108004 38 200918229 The apparatus of this embodiment is as shown in Fig. 10. The forward and backward movement of the plunger 40 will be performed by magnetic force. The apparatus of this embodiment is provided with the electromagnetic coil 67 of the moving mechanism of the plunger 40 in the drive unit 70. The front end of the micrometer 6 9 will form a core core, and the front end of the core will form a rear stop '52. The rear abutting portion 45 is made of a magnetic material. A coil spring 66 is disposed between the rear end surface of the piston chamber 6A and the rear end surface of the piston 44. In the apparatus of the present embodiment, when a current flows through the electromagnetic coil 67, the core is magnetized, and the magnetized core attracts the rear abutting portion 45' of the magnetic body to retract the plunger 40. When the rear abutting portion 45 has abutted against the rear stopper 52, the retreat of the plunger 40 is stopped. When the current is stopped in the electromagnetic coil, the rear stopper 52 loses the force of sucking the rear abutting portion 45, so that the plunger 40 is easily advanced by the elastic force of the coil spring 66. The apparatus of this embodiment will not require the sealing of the drive unit 7 because the front and rear movement of the plunger 40 does not utilize air. Therefore, the components constituting the plunger 40 are reduced in the rearward movement resistance, so that the plunger 4 can be smoothly moved. The remaining related constructions are as in Example i. The mechanism for moving the plunger 40 forward and backward may also have other configurations. For example, the plunger 40 can be moved forward and backward by a configuration in which both the front piston chamber 62 and the rear piston chamber 63 are supplied with air. The electromagnetic actuator fixed to the main body 71 may be connected to the rear of the plunger 4, and the plunger 40 may be moved forward and backward by only the expansion and contraction of the electromagnetic actuator. In this case, it is also preferable to use the front broadcast 51 to restrict the movement. That is, the plunger 4() is configured to advance at a high speed and to stop the advancement of the plunger 4 by abutting against the front stop 51. 97108004 39 200918229 [Embodiment 7] Embodiment 1 (4) is placed in a plunger rod When the front touch position of 41 is 12, it is convenient to use the front end 13 to block = if it does not leak from the discharge port 10, the state of the liquid material can be regulated. The liver is set in the following order. First, the electromagnetic switching room 72 is switched to the front = state. Rotate -32 to rotate the moving member; =: Move back and forth relative to the base member 27 =: ι is presented to the discharge port in the liquid chamber 14 1 〇上上="End 13 contact

The position becomes the contact position " the front end 13 of the plunger button 41 罝 罝 接触 contact position 12, and becomes the state of the nozzle U. At this time, in the present embodiment, as in the first embodiment, the column ΐ and the rear side move the sub-measured micro-meter 6 soil unit 7. The self-weight, front stop: gauge: Therefore, and use the coil magazine 66 to take the heart: 1 away from the square abutment 43, the poem b6 stops at the equilibrium position. In succession, the pneumatic batching machine 3 is used to press the air. However, in this state, since the plug should be blocked at the night: the upstream of the outlet 1 ,, the liquid material does not leak from the discharge port 22 from the right side while the maintenance device is inclined downward, so that the moving member 30 is moved. Move to the rear, and finally turn to the end of the body 7 ^ will be contacted. The rotary rotation button 32 of the movable member 3^ rotates to move the moving member 30 rearward to the right. Further, the rear side will move the 敕 敕 你 你 你 万 , ,, and the rotary button 32 will be known to make the body 71 toward the rear. Move, whereby the position of the front 97108004 200918229 stop 51 will also move backwards. On the other hand, since the plunger rod 41 is pushed forward by the coil spring 66, the plunger moves in the forward direction (4) before the front (four) portion 43, and the front end U is held to block the discharge port 1 and the right front stopper 51 abuts against the front abutment. In the second part (2), since the front side 曰 pushes the plunger rod 41 rearward, the body 7ι will move rearward together with the column yoke. In accordance with this, the front end of the plunger rod 41 is opposed to the upstream of the outlet 10. Since the pressurized air is supplied by the pneumatic batching machine 5, the liquid material is leaked from the discharge port 1 which has a gap. When the liquid material of the field is leaked from the discharge port 10, since the position of the front end 13 touches the position 12, the state before the instant is cut off to the state of the state. The moving member 30 is moved forward and the front side is stopped to slightly return to the front position as the "standard state". When the right side has been set in the specification state, the fixing screws 54A, 54β are locked, and the body 71 is fixed to the base member 27. The value of the memory 29 of the moving member 30 at the time of the normal state is memorized. Then, just like the embodiment! The stop position of the plunger rod 41 when entering and leaving is generally set. [Embodiment 8] The present invention is a configuration in which a liquid material storage container 5 for storing a liquid material is disposed at the lower end of the discharge device. Therefore, the liquid chamber 14 is not provided with the liquid material supply port, and the liquid material is directly supplied from the liquid material storage container 5. The discharge block 81 is sighed with a seal 18C' because it is not in contact with the liquid material during normal use, and thus 97108004 200918229 may not be provided. The liquid material storage container 5 is held by the base holding member (10) and the flange provided on the liquid material storage surface. Flange 85 disc flange with 捭:: The formed flange 95 is freely constructed. When the liquid material ρ Μ / holding member 86 is detachable, it can be ϋ gastric ϋ fIy k0 or replaced with other liquid materials. The liquid storage container 5 is replaced easily. The apparatus of the embodiment is also provided with the apparatus of the shifting example 1 in the setting gauge m (1). The long hole 53 is set as the actual stop position. After the row M, the implementation of the plunger 40 is performed. As in the apparatus of the first embodiment. Further, the plunger 4G which is movable by stopping the plunger 40 by the front stopper 51 can also be stopped by the correct position, and a sufficient inertial force is applied to the liquid material. For example, the pneumatic batching machine 3 as in the first embodiment can be used in the liquid material storage container 5, and the supply and discharge of air in the liquid material storage container 5 can be performed, and the liquid is applied - "m ll t night wood storage valley Pressurization and decompression of the liquid material in the benefit 5: The twisting and decompression performed by the pneumatic batching machine 3: can be moved in the forward and reverse movement of the plunger rod 41 in the same manner as in the second embodiment. The movable batching machine 3 is replaced with a pressing member such as a piston placed in a liquid storage container, or other pressure mechanism, and the liquid material in the liquid material: Zigujie 5 is pressurized and reduced.
