Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a discharge device for crushing a cartridge made of a flexible thin film or the like and discharging a fluid substance such as an adhesive or a caulking material contained therein.

[0002]

2. Description of the Related Art A discharge gun is one of conventional discharge devices of this type. The discharge gun includes a gun body, a piston provided on the gun body so as to be able to reciprocate, and a cylinder in which a pressing piece is slidably provided. A holding portion to be mounted is provided. When the cylinder is mounted on the holding portion, the axis of the cylinder coincides with the moving direction of the piston. Therefore, when the piston is moved forward, the piston enters the cylinder and moves the pressing piece.

[0003] When the discharge gun having the above configuration is used,
First, the cartridge is inserted into the cylinder, and the cylinder is mounted on the holding unit. Then, the piston is moved forward to move the pressing piece. As a result, the cartridge is crushed, and a fluid substance such as an adhesive is discharged from the tip of the cartridge. When the cartridge has been used up, first retract the piston and pull it out of the cylinder. Next, the cylinder is removed from the holder. Thereafter, the debris of the cartridge remaining at the tip of the holding unit is removed and discarded. Then, another cartridge is inserted into the cylinder and used again.

[0004]

In the conventional discharge gun, since the cylinder is attached to and detached from the gun body, there is a problem that it takes time to replace the cartridge. That is, when using a new cartridge, hold the cylinder with one hand and hold the cartridge with the other hand. Then, the cartridge is inserted into the cylinder. Thus, when the other hand is opened, the other hand holding the gun holds the gun body. Thereafter, the cylinder is mounted on the holding unit. When the soft cartridge has been used up, hold the gun body with one hand and remove the cylinder from the holder with the other hand. Then put the cylinder aside. When the other hand is thus held, the remaining soft cartridge is removed from the gun body with the other hand. As described above, in the conventional discharge gun, since the gun body and the cylinder cannot be handled at the same time, there is a problem that when replacing the cartridge, the gun body, the cylinder, and the cartridge must be changed. Also, since the cartridge is usually circular in cross section, if you remove it from the gun body and put it aside,
There was a problem of rolling.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides an apparatus body, a piston reciprocally provided on the apparatus body, and a pressing piece provided slidably inside the apparatus body. The piston is inserted into the cylinder to move the pressing piece, whereby the cartridge inserted into the cylinder is crushed and the fluid substance contained therein is removed from the cartridge. In a discharge device that discharges from a distal end portion, the cylinder is provided so as to be movable in a reciprocating direction of the piston with respect to the device main body and rotatable about an axis orthogonal to the reciprocating direction of the piston. And
In this case, it is desirable to arrange the rotation axis of the cylinder at the center in the longitudinal direction of the cylinder. The device main body is
In the case of having a pair of support arms extending along the reciprocating direction of the piston, the cylinder is disposed between the pair of support arms, and both sides of the cylinder are connected to the pair of support arms. It is desirable to be supported so as to be movable in the longitudinal direction and rotatable about an axis extending in a direction orthogonal to the pair of support arms. In the case where a nozzle mounting portion is provided at the distal end portions of the pair of support arms, the nozzle mounting portion is connected to the distal end portion of the cartridge and discharges a fluid substance contained therein. Preferably, a nozzle is provided, and the nozzle mounting portion is rotatably supported by the support arm about an axis extending in a direction orthogonal to the pair of support arms. The nozzle mounting portion is provided so as to be movable in a predetermined range in the longitudinal direction of the support arm, and when moved to the distal end side of the support arm, is non-rotatably supported by the support arm, and to the rear end side of the support arm. It is desirable that the support arm be rotatably supported by the support arm when moved.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to FIGS. In this embodiment, a discharge gun (discharge device) according to the present invention is shown in FIGS.
The cartridge 100 shown in FIG. 9 is used for the discharge gun 1. Of course, the present invention can be applied to a discharge device other than the discharge gun 1 and can be used for a cartridge other than the cartridge 100, for example, a cartridge 200 shown in FIG.

For convenience of explanation, first, the cartridge 100
The cartridge 100 includes a cylindrical main body 110 formed of one or more layers of thin films, a reinforcing cylindrical portion 120 provided at a front end opening of the main body 110, and a rear end opening of the main body 110. And a bottom portion 130 for closing. The main body 110 is formed in a tapered shape so as to gradually decrease in diameter from the front end side to the rear end side, but may be formed in a straight cylindrical shape.
The reinforcing cylinder 120 has a discharge port 121 at the center. The inner diameter of the discharge port 121 gradually decreases from the outside to the inside, and the opening inside the discharge port 121 is closed by a seal member 122 formed of a thin film. As will be described later, the seal member 122 is broken by the insertion tube 63 of the nozzle 6 fitted to the discharge port 121. As a result, a fluid substance such as an adhesive contained in the cartridge 100 can be discharged from the discharge port 121 to the outside through the nozzle 6.

Next, a discharge gun 1 for discharging a fluid substance from the cartridge 100 will be described. As shown in FIGS. 1 to 4, the discharge gun 1 has a gun body 2. The gun body 2 is provided with a grip 21 and an operation lever 22. Operation lever 22 is shown in FIG.
, The rod 23 advances by an amount corresponding to the amount of rotation, and the piston 3 provided at the tip of the rod 23 advances. When the operating lever 22 is released, the operating lever 22 is returned to the original position by the spring 24.
By repeating this, the rod 23 and the piston 3 can be advanced. The rod 23 and the piston 3 that have moved forward can return to the rear by rotating the locking lever 25 in the direction of arrow B against the urging force of the spring 26 and maintaining that state. Since such a structure is the same as that of the conventional discharge gun, a detailed description thereof will be omitted.

The gun body 2 has a disk-shaped support plate 27.
Is provided. The support plate 27 is arranged so that the rod 23 penetrates a central portion thereof. In addition, the support plate 27 is mounted around the center of the gun body 2.
It is provided so as to be rotatable. However, since there is a predetermined amount of frictional resistance between the support plate 27 and the gun body 2, the support plate 27 does not rotate freely and can be stopped at the intended rotation position. On the outer circumference of the support plate 27, the base ends of the pair of support arms 4 and 4
The arrangement is fixed at a distance of 0 °. The support arms 4, 4
The rod 2 is disposed at the same distance from the rod 23,
3 (parallel to the longitudinal direction of the piston 3).

A nozzle mounting member (nozzle mounting portion) 5 is provided at the tip of each of the support arms 4 and 4. As shown in FIG. 7, the nozzle mounting member 5 includes a circular end plate portion 51,
A substantially semi-cylindrical holding cylinder portion 52 formed on the rear end surface of the end plate portion 51. One side portion and the other side portion of the outer peripheral surface of the holding cylinder portion 52 have a square cross section. Shaft part 5
3 and 53 (only one shaft 53 is shown) are provided. Each of the shaft portions 53 is inserted into long holes 41, 41 (only one of the long holes 41 is shown) formed at the tip of the support arms 4, 4. Each elongated hole 41 extends in the longitudinal direction of the support arm 4, and the width of the distal end portion is formed to be the same as the width of the shaft portion 53. The rear end of the long hole 41 is formed in a circular shape, and its diameter is substantially the same as the length of the diagonal line of the shaft 53. Therefore, the shaft portion 53 can move in the longitudinal direction of the long hole 41, cannot rotate when inserted into the front end portion of the long hole 41, and is inserted into the circular rear end portion of the long hole 41. In the state of being turned, it becomes rotatable. Therefore, when the nozzle mounting member 5 moves toward the distal end within the length range of the long hole 41, it is non-rotatably supported by the support arms 4 and 4, and rotatably supported when it moves toward the rear end. You.

The nozzle 6 is detachably mounted on the nozzle mounting member 5. As shown in FIG. 7, the nozzle 6 has a tapered nozzle portion 61 and a disk-shaped flange portion 62 formed at the rear end of the nozzle portion 61.
And an insertion tube 63 formed on the rear end face of the flange 62. The nozzle 61, the flange 62 and the insertion tube 63 are formed concentrically,
1 and the insertion tube portion 63 communicate with each other. On the other hand, a pair of support arms 4 is provided on the end plate portion 51 of the nozzle mounting member 5.
An insertion groove 54 opened in a direction orthogonal to the line connecting 4 is formed, and a semicircular ridge 55 opened in the same direction as the insertion groove 54 is formed on the inner peripheral surface of the holding cylinder portion 52. ing.
Then, the base end of the nozzle portion 61 is inserted into the insertion groove 54 from its open portion, and the flange portion 62 is inserted between the end plate portion 51 and the ridge 55, so that the nozzle 6
Are detachably mounted on the nozzle mounting member 5. When the ejection gun 1 is dedicated to the cartridge 100, the nozzle 6 may be fixed to the nozzle mounting member 5 or provided integrally therewith.

The outer diameter of the insertion tube 63 of the nozzle 6 is slightly smaller than the inner diameter of the outer end of the discharge port 121, but is substantially the same as or slightly larger than the inner diameter of the inner end. Therefore, the insertion tube portion 63 is fitted to the inner end of the discharge port 121 in a press-fit state. Therefore, the fluid substance does not leak from between the inner peripheral surface of the discharge port 121 and the outer peripheral surface of the insertion tube 63. Moreover, by inserting the insertion tube 63 into the discharge port 121, the nozzle 6 and the cartridge 100 are inserted.
Are connected with a certain amount of frictional resistance. Also,
As shown in FIG. 9, when the insertion cylinder 63 is inserted into the discharge port 121 until the flange 62 abuts on the reinforcing cylinder 120, the insertion cylinder 63 is cut off at an angle. The longest part of the
The length of each of the shortest portions is set so as to protrude into the main body 110 from the opening on the inner side of 1 and stay in the discharge port 121. Therefore, when the insertion tube portion 63 is inserted into the discharge port 121, a part of the seal member 122 is pierced by the insertion tube portion 63, but is not pierced annularly. This is because when the seal member 122 is pierced in an annular shape, a substantially circular broken piece may enter the nozzle 6 and clog the nozzle 6, and in order to prevent such a situation, one of the seal members 122 may be used. I try to break through only the part.

A cylinder 7 is arranged between the pair of support arms 4 and 4 at an intermediate portion in the longitudinal direction. The cylinder 7 has a straight cylindrical shape with a circular cross section,
The inner diameter is substantially the same as the outer diameter of the tip of the main body 110 of the cartridge 100, that is, the maximum outer diameter of the main body 110. Therefore, the main body 110 of the cartridge 100 can be inserted into the cylinder 7 from the rear end until the reinforcing cylinder 120 abuts on the end face.

The cylinder 7 is supported by a pair of support arms 4 and 4 so as to be movable in the longitudinal direction and rotatable. That is, as shown in FIGS. 1 to 6 and FIG.
A relatively thick reinforcing member 7 is provided on the outer peripheral surface of the cylinder 7.
1, 71 are arranged and fixed at a distance of 180 ° in the circumferential direction. At the center of each reinforcing member 71, 71, a screw member 7 is provided.
2, 72 are screwed. The screw members 72 and 72 are arranged so that their respective axes are aligned with each other and are also aligned with the diameter line of the cylinder 7.
1 is screwed and fixed to the protection member 71 in a state of being substantially the same as the thickness of the support arm 4 from the support member 4. On the other hand, a support hole 42 extending in the longitudinal direction is provided at the center of the support arm 4.
Are formed. The shaft portion 72b of the screw member 72 is movably and rotatably inserted into each support hole. Thus, the central portion of the cylinder 7 is rotatably supported by the pair of support arms 4 and 4 about an axis (screw member 72) oriented in a direction orthogonal to the longitudinal direction.

As shown in FIGS. 2 to 4, a pressing piece 8 is slidably provided inside the cylinder 7. The pressing piece 8 is a cartridge 100 inserted into the cylinder 7.
The rear end portion is pressed to crush the main end portion 110, and is pushed and moved forward by the piston 3. When the pressing piece 8 is crushed until the cartridge 100 is used up, the pressing piece 8 moves to the end of the cylinder 7. When a new cartridge 100 is inserted from the other end of the cylinder 7 in this state, the bottom 130 of the cartridge 100 almost comes into contact with the pressing piece 8, or a slight gap is formed between them. . This is the same whether the pressing piece is moved to one end of the cylinder 7 or to the other end. Therefore, after the pressing piece 8 is moved to one end of the cylinder 7 until the cartridge 100 is used up, when a new cartridge 100 is inserted into the cylinder 7, the cartridge 100 is moved from the other end of the cylinder. It only has to be inserted, and there is no need to return the pressing piece 8 to its original position.

When discharging the fluid substance contained in the cartridge 100 using the discharge gun 1 having the above-described structure, the nozzle 6 is mounted on the nozzle mounting member 5 in advance, and the movable piece 8 is Move to one end. Next, as shown in FIG. 2 and FIG.
The cylinder 7 is moved rearward until the... Hits the rear end of the support hole 42, and the cylinder 7 is turned to be directed in a direction perpendicular to the support arms 4 and 4. In this case, the cylinder 7 may be moved and rotated in any order. However, as described later, when the used cartridge 100 is replaced with a new cartridge 100, the cylinder 7 is moved rearward. Then, rotate. When rotating the cylinder 7, it is preferable that the support arms 4 and 4 are oriented in the horizontal direction, one end where the moving piece 8 is fitted is directed downward, and the other end opening of the cylinder 7 is directed upward.

Next, the cartridge 100 is inserted through the opening at the other end of the cylinder 7. Of course, the cartridge 100
Is inserted into the cylinder 7 from the rear end. After the cartridge 100 is inserted until the reinforcing cylinder 120 comes into contact with the other end surface of the cylinder 7, the cylinder 7 is rotated until it becomes parallel to the support arm 4, and the reinforcing cylinder 120 faces the nozzle mounting member 5. Thereafter, the cylinder 7 is advanced. The advance of the cylinder 7 may be performed by hand, or may be performed by pushing the pressing piece 8 forward by the piston 3. The cylinder 7 is advanced until the reinforcing cylinder 120 hits the ridge 55 of the nozzle mounting member 5. Then, the insertion cylinder 63 of the nozzle 6 is
21 and breaks the seal member 122. Thereby, the fluid substance in the cartridge 100 can flow into the nozzle 6.

Next, as shown in FIG. 4, the piston 3 is advanced and the bottom 1 of the cartridge 100 is
30 is pushed forward. Then, cartridge 1
00 is squashed into an accordion from the rear end,
The fluid substance contained in the cartridge 100 is discharged from the nozzle 6.

When the entire body 110 of the cartridge 100 is crushed and the cartridge 100 is used up, the piston 3 is moved rearward as shown in FIG.
Extract from Thereafter, the cylinder 7 is moved backward. At this time, since the insertion cylinder portion 63 of the nozzle 6 is fitted into the crushed ejection port 121 of the cartridge 100 in a press-fit state, the cartridge 100 is
Is fixed via the nozzle 6 and moves relatively out of the cylinder 7 as the cylinder 7 moves backward. Next, as shown in FIG. 6, after the nozzle mounting member 5 is moved forward, the nozzle mounting member 5 is turned by approximately 90 ° to turn the used cartridge 100 downward. At this time, cylinder 7
May be parallel to the support arms 4, 4, but it is preferable that the cartridge 7 is oriented vertically so that the cylinder 7 does not hinder the removal of the cartridge 100.
After that, the holding cylinder 5 in the outer peripheral surface of the reinforcing cylinder 120
The portion exposed from the open portion of No. 2 and the notch portion 52 a formed on the outer peripheral surface thereof is sandwiched between two fingers, and the cartridge 100 is removed from the nozzle 6. At this time, since the whole used cartridge 100 is located below the support arms 4, 4, the support arms 4, 4 hinder the gripping of the reinforcing tubular portion 120 and the removal of the cartridge 100 from the nozzle 6. Never be. Therefore, the cartridge 100 can be easily removed from the nozzle 6. When the used cartridge 100 is removed, the entire discharge gun 1 returns to the state shown in FIG.
A new cartridge 100 is inserted into the cylinder 7 and used for a new ejection.

As described above, in the discharge gun 1 according to the present invention, since the cylinder 7 is rotatably mounted on the support arm 4, the gun body 2 is held by one hand and the cartridge 100 is held by the other hand. The cartridge 100 can be inserted into the cylinder 7 while holding each of them. Therefore, there is no need to change the gun body 2, the cylinder 7, and the cartridge 100 at all. When the cartridge 100 is used up, the gun body 2 is held with one hand.
And the cylinder 7 with the other hand. When the other hand is released after the cylinder 7 is moved rearward, the cylinder 7 is supported by the one hand via the gun body 2.
Therefore, there is no need to place the cylinder 7 aside, and it is possible to prevent the cylinder 7 from rolling.

The present invention is not limited to the above-described embodiment, and the design can be changed as appropriate. For example, a cartridge 200 shown in FIG. 10 can be used in place of the cartridge 100. Cartridge 200
The main body 210 is the same as the main body 110 except that the main body 110 has a constant outer diameter. Combined nozzle part 230 and main body part 21
And a metal fitting 240 for closing the opening at the rear end of the nozzle portion 230. When used for the discharge gun 1, an appropriate portion at the tip of the nozzle portion 230 is cut off and opened.

The discharge gun for discharging the cartridge 200 has the same configuration as the discharge gun 1 except for the following points. That is, the cartridge 200 is
30, there is no need to mount the nozzle 6 on the nozzle mounting member 5.
The discharge port 230 is inserted into the insertion groove 54, and the end plate 61 is inserted between the reinforcing cylinder 220 and the nozzle 230. As a result, the position of the nozzle portion 230 is fixed to the nozzle mounting member 5, and the position of the cartridge 200 is fixed. As described above, in the ejection gun for the cartridge 200, since the ridge 55 is unnecessary, the ridge 55 is unnecessary.
Is formed separately from the nozzle mounting member 5 so as to be detachable, the discharge gun 1 can be used also for the cartridges 100 and 200.

In order to discharge a fluid substance from the cartridge 200 by using the discharge gun having the above-described structure, the cartridge 7 is inserted into the cylinder 7 shown in FIG. Rotate until In this case, the cylinder 7 is rotated while adjusting the position in the front-rear direction, so that the discharge port 221 is inserted into the insertion groove 54 and the end plate 51 is fitted between the reinforcing cylinder 220 and the nozzle 230. . Then, the cartridge 100
The fluid substance is discharged from the cartridge 200 in the same manner as in the above case. When the cartridge 200 has been used up, the cylinder 7 is moved backward, and the cartridge 200 is pulled out of the cylinder 7. Thereafter, the cartridge 200 is moved upward with the nozzle portion 6 and the cartridge 20 is moved upward.
0 is removed from the nozzle mounting member 5. Therefore, in this case, there is no need to rotate the nozzle mounting member 5.
Other procedures are the same as those when the cartridge 100 is used.

[0024]

As described above, according to the discharge apparatus of the present invention, every time the cartridge is replaced, the gun body, cylinder, and cartridge must be changed, or the cylinder must be attached to and detached from the apparatus body. This has the effect of saving time and labor and reliably preventing the cylinder from rolling.
