Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an extrusion apparatus capable of simultaneously extruding a two-component reaction-curable material typified by a two-component adhesive, which is housed in two tubes separately, and the extrusion device. The present invention relates to a coating device provided with a nozzle portion, which discharges a two-liquid reaction curable material extruded by a device in a combined state.

[0002]

2. Description of the Related Art Conventionally, a two-component adhesive extruding device, which is a typical example of a two-component reaction-curing material, and a coating device using the same are two liquids between three holding plates facing each other in parallel. Two tubes of mold adhesive are sandwiched, and a screw rod that has a reverse thread at the center is made to penetrate these three holding plates and screwed into the screw holes of the two outer holding plates. By rotating the screw rod and narrowing the gap between the two outer holding plates, an extrusion device that can push out the adhesive from both tubes at the same time and a nozzle part connected to each tube using this extrusion device There is known a coating device that can discharge both adhesives that have been provided and extruded by combining them at a nozzle portion (1990 Utility Model Publication No. 138183).

Further, an extrusion apparatus provided with two cylinder-shaped cartridges which separately store a two-component adhesive, and two grip rods, a lever portion and two push rods each having a piston-like push portion at the tip thereof. Using this extrusion device, a nozzle part connected to the tip of the cartridge is provided, and the two cartridges are attached to the extrusion device with the two push rods pulled out rearward, and the lever part is held by holding the grip part. There is known a coating device in which the adhesive in each cartridge is pushed out to the nozzle portion by the push-out portion so as to be joined and discharged (Japanese Utility Model Publication No. 80563 in 1993).

[0004]

However, in the case of the extrusion device for pushing out the adhesive from the tube and the coating device using the same, the device itself is held by one hand and the screw rod is turned by the other hand to push the adhesive. You will need to use both hands when working. Further, when the screw rod is rotated, the extrusion device is swayed and the discharge position is easily displaced, which causes a problem of poor workability.

Further, in the case of an extrusion device for extruding an adhesive from the cartridge and a coating device using the same, a two-component adhesive contained in a dedicated cartridge is separately manufactured, or is generally sold as a tube. It is necessary to refill the existing two-component adhesive into a special cartridge before use. When a two-component adhesive stored in a dedicated cartridge is separately manufactured and used, the cartridge portion that functions as a cylinder must be disposable,
There is a problem that the cost is higher than that of a tube, and there is a problem that refilling is troublesome.

The present invention has been made in view of the above-mentioned problems of the related art, and it is inexpensive and widely used in tubes.
An object of the present invention is to provide an extruding device capable of simultaneously extruding a liquid reaction curable material in a tube with one hand and improving the workability of a coating operation by a coating device using this.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described in more detail with reference to the drawings.

FIG. 1 shows a coating apparatus A according to a first example of the present invention.
Is a side view and FIG. 2 is a plan view thereof.

As shown in the figure, the coating apparatus A of this example is
It is composed of a nozzle portion B and an extrusion device C.

First, the nozzle portion B will be described.

The nozzle part B is detachably connected to two tubes 2 located on the substrate 1 of the extrusion device C,
Each of the two-liquid reaction-curable materials extruded from each tube 2 is merged and discharged, and is composed of a nozzle body 3 and a guide tube 4. The nozzle body 3 is detachably connected to the tip of the guide tube 4. The rear end side of the guide tube 4 is branched toward the mouths 5 of the two tubes 2, and the branched branches are connected to the tube 2. The guide tube 4 guides the materials extruded from the tubes 2 to the nozzle body 3 without joining them, and both materials are joined and discharged in the nozzle body 3.

By the way, the guide tube 4 is replaced by the two tubes 2.
The reason why the material from (1) is guided to the nozzle body 3 without being merged is to prevent the material from hardening in the guide tube 4 when the use is interrupted or stopped halfway. If the guide tube 4 and the nozzle body 3 are disposable or both are cleaned after each use, both materials may be joined in the guide tube 4. However, as in this example, both materials are prevented from merging in the guide tube 4,
Moreover, it is preferable that the nozzle body 3 is detachable from the guide tube 4 because the guide tube 4 can be repeatedly used and only the nozzle body 3 needs to be cleaned after use.

The guide tube 4 and the nozzle body 3 are made of a material which is not deteriorated by the two-liquid reaction hardening type material. As the constituent material of the guide tube 4, for example, polyacetal, polypropylene, polyester, etc. can be used in addition to aluminum, stainless steel, etc. Further, as the constituent material of the nozzle body 3, low density polyethylene,
High density polyethylene, polypropylene, polyester,
Although polyacetal or the like can be used, low density polyethylene is particularly preferable.

The joint between the mouth portion 5 of each tube 2 and the guide tube 4 is formed by forming a flange portion 6 at the end of the guide tube 4 and engaging with the flange portion 6, as shown in an enlarged view in FIG. The cap nut-shaped cap 7 is screwed into the mouth portion 5 and tightened so that the distal end surface of the guide tube 4 and the tip end surface of the mouth portion 5 are brought into close contact with each other.

Next, the extruder C will be described.

In FIGS. 1 and 2, reference numeral 1 is a substrate, which is a substrate 1.
A grip portion 8 and a lever portion 9 positioned in front of the grip portion 8 are provided on the lower surface side of the grip portion 8. The lever portion 9 is interlocked with a pressing plate tilting means 10 described later. Further, on the substrate 1, two tubes 2 made of a two-component reaction-curable material are held with their mouths 5 facing forward.

On the base plate 1, the rear end is pivotally attached to the rear end of the base plate 1 by a butterfly plate 11, and the holding plate 1 which can be tilted up and down on the base plate 1.
2 is provided, and the body portion 13 of both tubes 2 is sandwiched between the substrate 1 and the substrate 1.

A grip portion 8 is provided in front of the lever portion 9.
A pressing plate tilting means 10 is provided integrally with the lever portion 9. The holding plate tilting means 10 is provided with a slide shaft 14 whose upper end is connected to the front end of the holding plate 12 with play in the front-rear direction, and pulls down the slide shaft 14 when the lever 9 is squeezed. Thus, the pressing plate 12 is tilted downward. That is, when the slide shaft 14 is gradually pulled down in a stepwise manner by repeatedly pulling the lever portion 9 and releasing it, the holding plate 12 tilts downward, and finally the state shown in FIG. 3 is obtained. Become. As shown in FIG. 3, when the central portion of the front portion of the substrate 1 is formed as a recessed portion 15 which is recessed downward, and the shoulder portions 16 of both tubes 2 are located on the recessed portion 15, a normally hard shoulder is obtained. The portion 16 escapes into the recess 15 and the body portion 13 is easily crushed uniformly.

Based on FIGS. 5 to 7, the holding plate tilting means 1 is provided.
0 will be further described.

The holding plate tilting means 10 includes the substrate 1 (see FIG. 1).
(See FIG. 3), the slide shaft 14 projecting downward has a push-down plate 17 and a stopper plate 18 which slidably penetrate.

As clearly shown in FIG. 5, the push-down plate 17 has the slide shaft 14 penetrating toward one end thereof,
A pressing pin 19 that tilts downward when the lever portion 9 is drawn is abutted on the upper surface of the other end side, and the other end side of the push-down plate 17 is pressed downward when the lever portion 9 is drawn. It is supposed to be done. Also, the push-down plate 17 is
It is pressed upward by the first spring 20. The pressing plate 17 is pressed by the pressing force of the first spring 20.
When the lever portion 9 is not squeezed, it is in a sliding posture that allows the slide shaft 14 to slide. That is,
A hole formed in the push-down plate 17 for penetrating the slide shaft 14 is oriented in a direction that allows the slide shaft 14 to slide in the axial direction.

On the other hand, as shown in FIG. 6 in particular, the stopper plate 18 has the slide shaft 14 penetrating its intermediate portion, and one end thereof is opened to the case 21 integral with the grip portion 8. It is supported by the support hole 22, and the other end extends outside the case 21. Further, since the stopper plate 18 is pressed upward by the second spring 23 and is inclined upward with the support portion of the support hole 22 as a fulcrum, when the lever portion 9 is not squeezed, It is in a meshing posture that meshes with the slide shaft 14 and prevents the slide shaft 14 from sliding. That is,
Since the stopper plate 18 is inclined upward, the hole formed in the stopper plate 18 for penetrating the slide shaft 14 meshes with the slide shaft 14 at the peripheral edge of the hole, so that the slide shaft 14 moves in the axial direction. The posture is such that the slide is blocked.

When the lever portion 9 is pulled down from the state shown in FIG. 5 as shown in FIG. 7, the end portion of the push-down plate 17 is pushed downward by the push pin 19, so that the push-down plate 17 slides first. It is slightly tilted downward with the penetrating portion of the shaft 14 as a fulcrum. This slight downward tilt causes the push-down plate 17 to be in the same meshing posture as the stopper plate 18. Therefore, the push-down plate 17 after that
The first spring 2 by the drawing of the lever portion 9.
It is pushed down together with the slide shaft 14 against 0.

On the other hand, when the slide shaft 14 starts to slide downward as described above, the stopper plate 18
Since it has been in the meshing posture until then, it initially tilts slightly downward against the second spring 23 together with the slide of the slide shaft 14, and as a result, similar to the push-down plate 17 of the lever portion 9 before the drawing aperture. In a sliding position,
The slide shaft 14 is allowed to slide further downward.
Accordingly, the slide shaft 14 is slid downward by an amount corresponding to the pulling amount of the lever 9 as the lever 9 is pulled, and the tip of the pressing plate 12 (see FIGS. 1 to 3) is pulled downward. Become.

If the pulling force of the lever portion 9 is released after pulling the lever portion 9 by the necessary amount, the force for pushing the slide shaft 14 downward is lost, so the stopper plate 18
Is pushed up by the pressing force of the second spring 23 and immediately returns to the original meshed state. In this state, the force to slide the slide shaft 14 upward causes the stopper plate 18 to further tilt with the support portion of the support hole 22 as a fulcrum, and the stopper plate 18
And the engagement of the slide shaft 14 with each other will be strengthened.
It is possible to reliably prevent the slide shaft 14 from sliding upward. That is, the slide shaft 14 is prevented from returning due to the repulsive force of the tube 2 (see FIGS. 1 to 3) pressed by the holding plate 12 (see FIGS. 1 to 3).

On the other hand, the push-down plate 17 is pushed up by the first spring 20 as a result of the release of the pushing force by the push pin 19, returns to the sliding posture, and is further slid upward by the stopper plate 18. It returns to its original position while sliding with respect to the blocked slide shaft 14. At this time, the push pin 19 is also pushed up at the same time,
The lever portion 9 will be returned to the state before the drawing.

If the portion of the stopper plate 18 extending outside the case 21 is pressed downward in the state where the lever portion 9 is not drawn tight, the stopper plate 18 can be brought into a sliding posture and the slide shaft The front end portion of the pressing plate 12 (see FIGS. 1 to 3) can be lifted upward by sliding 14 upward.

One end of the stopper plate 18 in this example is
It is supported by a support hole 22 opened in the case 21 and serves as a fulcrum for tilting in the vertical direction. This fulcrum is the support hole 22.
Since it has a size with some allowance in the vertical direction, it has play in the vertical direction. With this arrangement, the fulcrum-side end of the stopper plate 18 that has been moved to the lower end side of the support hole 22 when the lever portion 9 is drawn and squeezed causes the support hole to move when the pulling and drawing force of the lever portion 9 is released. After moving to the upper end side of 22, the stopper plate 18 returns to the engaged posture. Therefore, when the pulling and drawing force of the lever portion 9 is released, the holding plate 12 (see FIGS. 1 to 3) is pushed up by the amount of this play due to the elastic force of both tubes 2 (see FIGS. 1 to 3). become. By this, the pressure in both tubes 2 immediately after the pulling force of the lever portion 9 is released can be relieved, and both materials flow out from the nozzle body 3 until after the pulling force of the lever portion 9 is released. It is possible to prevent that. Further, the auxiliary spring 24, which presses the vicinity of the fulcrum of the stopper plate 18 downward, is provided when the lever plate 9 is pulled down.
This is for surely moving the fulcrum side end of 8 to the lower end side of the support hole 22.

As described above, the fulcrum of the stopper plate 18 in this embodiment is constituted by supporting the end portion of the stopper plate 18 in the support hole 22, which is supported in the vertical direction of the stopper plate 18. It is not limited to the support hole 22 as long as it serves as the fulcrum of the tilting of the above, but may be supported by using a shaft pin (not shown).
In the case of the support using the shaft pin, the play can be provided by loosely mounting the shaft pin.

Next, referring to FIGS. 8 and 9, the second aspect of the present invention will be described.
The coating apparatus A ′ according to the example will be described.

The coating apparatus A'of this example is the same nozzle section B as that of the first embodiment described above, and an extrusion apparatus C'having a holding plate tilting means 10 'different from that of the first embodiment described above. It consists of Holding plate tilting means 1 in the second example
0'is provided with a slide plate 25 and a claw portion 26 that transmit the force of pulling the lever portion 9 to the holding plate 12 as a force to tilt the holding plate 12 downward. 8 and 9, the same reference numerals as those in FIGS. 1 and 2 indicate the same members.

The lower end of the slide plate 25 is pivotally attached to the lever portion 9 by a connecting pin 27, and is slid up and down by the operation of the lever portion 9. The slide plate 25 penetrates the base plate 1 and the holding plate 12, and the holding plate 12 Protruding above. Slide plate 2
5 has a downward saw blade portion 28 on the front surface side, and is elastically pressed forward by a curved plate spring 29 attached to the holding plate 12. Further, on the front side of the slide plate 25, the claw portion 2 attached to the pressing plate 12 is provided.
6 is located, and the claw portion 26 and the blade of the saw blade portion 28 of the slide plate 25 mesh with each other.

To explain further, when the lever portion 9 is pulled down, the slide plate 25 is slid downward. At this time, the blade of the saw blade portion 28 is pushed by the plate spring 29 and meshes with the claw portion 26, so that the holding plate 12 slides while pulling it downward, and both tubes 2 are moved in accordance with the amount of drawing of the lever portion 9. Crushed. On the other hand, when the pulling force of the lever portion 9 is released, the lever portion 9 is returned by the force of the lever spring 30, and the slide plate 25 slides upward with this return. At this time, since the saw blade portion 28 faces downward, the saw blade portion 28 rubs through the claw portion 26 while tilting the slide plate 25 rearward against the leaf spring 29, and the slide plate 25 slides upward. Is not obstructed by the claw portion 26.

By the way, when the tubes 2 are squeezed to some extent by pulling the lever portion 9, the holding plate 12 is tilted to a position lower than the previous state (a position closer to the substrate 1). In this state, when the pulling force of the lever portion 9 is released and the slide plate 25 is slid upward, the slide plate 25 returns to a substantially previous position, so that the lever portion 9 is engaged with the claw portion 26 when pulling. The blade below the blade of the saw blade portion 28 that has been engaged is newly engaged with the claw portion 26. Therefore, it is possible to squeeze both tubes 2 gradually and to extrude two kinds of materials at the same time only by repeatedly drawing the lever portion 9 and releasing it.

Examples of the two-component reaction-curable material applicable to the present invention include typical two-component adhesives, two-component caulking materials, sealing materials, paints and the like. Examples of the two-component adhesive include a polymerization reaction curable adhesive such as an acrylic adhesive, an unsaturated polyester adhesive, a vinyl ester adhesive, an epoxy adhesive, and a urethane adhesive. Among these, acrylic adhesives are preferable because high adhesive strength is easily obtained even if the two materials are not joined sufficiently.

For a two-component reaction-curable material (for example, an epoxy adhesive) which requires a sufficient mixing of the two materials, it is preferable to use the nozzle body 3 having a built-in static mixer.

On the other hand, in the case of an acrylic adhesive, high adhesive strength can be obtained if the A agent and the B agent extruded from each tube 2 come into contact with each other to some extent. When targeting such a two-component reaction curable material, as shown in FIG. 10, the nozzle body 3 is assumed to have a flat discharge port 31, and both materials (A Agent and B
It is preferable that the agent) is extruded from a position sandwiching the flat extension region of the ejection port 31 so that both materials overlap each other in the extension region of the ejection port 31. In this way, both materials can be discharged while being in contact with each other in a state where reliable curing can be obtained, without incorporating a costly static mixer.

There are the following two types of nozzle portions B having the above-mentioned discharge form.

In the first type, as shown in FIG. 11A, the A agent 32a and the B agent 32b are extruded into the nozzle body 3 from a position sandwiching the extension area of the discharge port 31,
The area where the agent 32a and the agent B 32b overlap is extruded in a state of a thin laminate, and the curing area 33 contacts only the peripheral portion of the discharge port 31 of the nozzle body 3 and contacts the other inner peripheral surface of the nozzle body 3. It is a type that I decided not to do. Incidentally, the cured area 3
The term “3” refers to a region where the A agent 32 a and the B agent 32 b are hardened in the nozzle body 3 when extruded so as to overlap each other in the nozzle body 3.

In the case of the first type, if the nozzle body 3 is removed from the guide tube 4 after the work is interrupted or stopped for a long time and the hardening region 33 is hardened, as shown in FIG. The hardened area 33 remains attached to the guide tube 4 side in a plate shape, and the uncured A agent 32a and B agent 3 remain in the nozzle body 3.
It is removed with only 2b remaining. That is, since the hardened area 33 is almost not in contact with the nozzle body 3, the hardened area 33 is not bonded to the nozzle body 3 and the hardened area 3
3 is prevented from adhering to the inside of the nozzle body 3. Therefore, the hardening region 33 that remains in a plate shape at the tip of the guide tube 4 is formed.
It is possible to start the work using the same nozzle body 3 again by simply removing the uncured material and wiping the uncured A agent 32a and B agent 32b in the nozzle body 3, and the nozzle body 3 is used repeatedly. It is advantageous when

The second type is as shown in FIG. 12A, which is basically the same as the above,
This is a type in which the hardening region 33 is in contact with not only the peripheral portion of the discharge port 31 of the nozzle body 3 but also the front inner peripheral surface of the nozzle body 3.

In the case of the second type, when the nozzle body 3 is removed from the guide tube 4 after the hardening region 33 is hardened,
As shown in FIG. 12B, the cured region 33 is removed together with the uncured A agent 32a and B agent 32b in the nozzle body 3. That is, since the hardening region 33 is also in contact with the front inner peripheral surface of the nozzle body 3, it is bonded to the nozzle body 3. Therefore, dirt is unlikely to remain on the guide tube 4 side, and the work can be started by mounting a new nozzle body 3, which is advantageous when the nozzle body 3 is disposable.

In both the first type and the second type, as shown in FIG. 10, a ridge 34 (protruding length) is formed on the distal end surface of the guide tube 4 in a direction parallel to the flat discharge port 31. Is preferably about 1 to 10 mm) to promote the overlapping of both materials in the extension region of the ejection port 31.

FIGS. 13 and 14 show another example of the nozzle body 3, in which the lower side of the discharge port 31 is an inclined guide surface 35 which is continuous with the discharge port 31. As shown in FIG. 14, the guide surface 35 is in contact with the application surface 36, and makes it easy to apply both the extruded materials with a constant thickness and at a desired position.

[0047]

The present invention is as described above, and the two-component reaction curable material is extruded from each tube 5 by simply grasping the grip portion 8 with one hand and pulling the lever portion 9 to squeeze the nozzle portion B. Since it can be discharged from one, the work can be done with one hand. In addition, since the work is performed with one hand of gripping the grip portion 8 and pulling down the lever portion 9, it is easy to discharge the adhesive while moving the tip of the nozzle portion B along the intended position, which is excellent in workability. Accurate application of adhesive is possible.
