Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a dispensing device for supplying a viscous agent such as a sealant using pressurized gas.

[Prior art]

A conventional viscous agent dispensing device of this type has a gas chamber and a seat at the base, opens the gas chamber, and provides a latch on the seat, and a viscous agent filling cylinder is inserted into the opening of the gas chamber. The rear end portion was inserted and the discharge port portion of the viscous agent filling cylinder was latched to the latching portion of the seat.

Viscous agent filling cylinders having different lengths are adjusted by moving the seat forward and backward.

However, in such conventional viscous agent dispensing devices, the movement of the catch is made by sliding the catch and locking it with a screw, making it difficult to adjust and make fine adjustments. .

[Purpose of the invention]

This invention was made based on this situation,
The purpose is to provide a viscous agent dispensing device that allows easy adjustment of the forward and backward movements of the catch and also allows fine adjustment of such forward and backward movements.

[Structure of the invention]

This purpose was to provide a gas chamber and a catch at the base.
While opening the gas chamber, the receiver is provided with a latch part on the seat, and the rear end of the viscous agent filling cylinder is fitted into the opening of the gas chamber, and the viscous agent filling cylinder is inserted into the latching part of the seat. In a viscous agent dispensing device in which the discharge port is locked, this was achieved by installing the seat so that it can move forward and backward depending on emotion.

[Explanation of Examples]

The present invention will be described in detail below based on FIG.

In the figure, 11 is the base of the viscous agent dispensing device, 13 is a gripping tube screwed to this base 11, and 15 is this gripping tube 1.
This is a lid that covers the opening of No.3.

17 is an opening mechanism, and 19 is a pressure reducing valve, each of which is installed inside the grip tube 13. The unsealing mechanism 17 unseals the carbon dioxide gas cylinder 21 housed in the grip cylinder 13, and the pressure reducing valve 19 gradually reduces the pressure of the high-pressure carbon dioxide gas flowing out from the carbon dioxide gas cylinder 21 into the carbon dioxide gas cylinder.

Reference numeral 23 denotes a through hole, which is bored in the upper part of the grip tube 13 in the base 11. Further, 25 is an on-off valve, and the through hole 2
It is formed in the middle of 3. This on-off valve 25 controls pressurized gas sent to a gas chamber 39, which will be described later. 27
is a valve rod that constitutes the on-off valve 25, and is fitted into the through hole 23 so as to be movable forward and backward with its tip exposed. The valve rod 27 moves forward and backward as the operating lever 29 swings to open and close the on-off valve 25. Next, 39 is a gas chamber, which is formed at the rear of the base 11. This gas chamber 39 has an opening 4
2, and the rear part of the viscous agent filling cylinder P is fitted into this opening 42 via the sealing member S. The seal member S is made of an elastic material such as rubber, and includes a cylindrical body 47 having an outer flange 43 at the front end and an integrated inner bent piece 45 at the rear end periphery. The sealing member S has a cylindrical body 47 connected to the opening 42 of the gas chamber 39 and the viscous agent filling cylinder P.
By sandwiching the outer flange 43 between the inner edge of the opening 42 and the frame member 49, the outer flange 43 is fixed without any gap, and the rear end peripheral edge of the viscous agent filling cylinder P is connected to the cylinder 47 and the outer flange 43. It is held between the inner bent pieces 45.

Note that 33 is an exhaust valve, which releases pressurized gas from the gas chamber 39 by pushing a knob 37 against a compression spring 35.

On the other hand, 81 and 83 are support parts having through holes 85 and 85, and are installed at the lower part of the tip of the base part 11. This pair of support parts 81 and 83 have a predetermined interval. Reference numeral 87 denotes an adjustment screw, which adjusts the support portion 81. through small diameter portions at both ends.
It is rotatably fitted into the through holes 85, 85 of 83. This i1\M screw 87 has a shaft hole 89 in which a female threaded portion is formed. A pivot screw 91 corresponds to the pivot of the present invention, and is screwed into the shaft hole 89 of the adjustment screw 87. Therefore, by rotating the adjustment screw 87, the pivot screw 91
can move forward and backward. Reference numeral 51 denotes a seat having a notch 51a (corresponding to the latching portion of the present invention), and is fixed to the head of the pivot screw 91. This seat 51 fixes the viscous agent filling 1VJP by being hooked to the discharge portion of the viscous agent filling cylinder P via the notch 51a. Also,
Since the male thread of the pivot screw 91 is left-handed, the catch 51
When rotated in the latching direction (see Figure 2), the catch 51
moves backward (moves toward the gas chamber 39). As a result,
The discharge port of the viscous agent filling cylinder P is connected to the gas chamber 3 by the seat 51.
Since it is pressed in nine directions, the viscous agent filling cylinder P is fixed even more firmly. If the male threaded portion of the pivot screw 91 is right-handed, the direction in which the catch seat 51 is latched may be reversed from the direction described above (the direction shown in FIG. 2).

Further, 53 is a pouring control valve, which has a nozzle 55 at its tip and a fitting opening 57 at its rear end. Fitting port 5 of this pouring control valve 53
7 is fitted with a discharge port of a viscous agent filling cylinder P via an elastic tube 59 made of rubber. The pouring control valve 53 is latched onto the seat 51 with the viscous agent filling cylinder P fitted therein. A valve box 60 is formed between the nozzle 55 of the spout control valve 53 and the fitting opening 57.

This valve box 60 has a cylindrical shape and has a rod-shaped valve body 61 that can move forward and backward inside the body. 63 is a window, which is formed in the valve body 61. An elastic tube 59 fitted into the viscous agent filling cylinder P is fitted into the window 63 . 65 is a moving pin, and the rack is passed through this window 63. Therefore, this movable bottle 65 moves up and down as the valve body 61 moves back and forth. Further, 67 is a long hole, which is bored in the valve body 61. This elongated hole 67 is for inserting a fixing pin 69 mounted on the valve box 60. Note that this fixed pin 69 and the movable bin 6
5, the elastic tube 59 is inserted therebetween. Also, 71
is a compression spring, which is installed inside the valve box 60 and presses the valve body 61 upward. Therefore, the elastic tube 59 between the fixed pin 69 and the movable pin 65 is normally disconnected from communication.

Next, 73 is a flexible push-pull cable that connects the valve body 61 and the operating lever 29.

Therefore, when the valve rod 27 slides to the left (in the direction of the arrow) due to the operation of the operating lever 29, the valve body 61 is moved by the compression spring 7.
1, and the operation lever 29
When the operation is released, the valve body 61 is pushed upward by the elasticity of the compression spring 71, so that communication with the elastic tube 59 is cut off. At this time, the valve lever 27 is slid to the right by the compression spring (return spring) 25a of the on-off valve 25.

[Operation of the embodiment]

When the operating lever 29 is pulled in the direction of the arrow against the compression springs 25a and 71, the valve rod 27 slides to the left.Then, the on-off valve 25 opens and pressurized carbon dioxide flows into the gas chamber 39. ,
Press the bottom of the viscous agent filling cylinder P. At the same time, the pull cable 73 is pulled and the valve body 6 of the main control valve 53 is pulled.
I is pulled down and the closed elastic tube 59 is opened, so the viscous agent in the viscous agent filling cylinder P is poured out from the nozzle 55.

To stop dispensing the viscous agent, it is sufficient to release the pull on the operating lever 29. Then, the J[′ integral 61 is pushed upward by the elasticity of the compression spring 71, so
The elastic tube 59 is moved again by the moving pin 65 and the fixed pin 69.
communication is cut off. At the same time, pu, spurke ~ pu 7
3, the valve lever 27 slides to the right to close the on-off valve 25, thereby stopping the supply of pressurized carbon dioxide gas to the gas chamber 39.
