Abstract

PURPOSE:To smoothly inject a viscous agent such as a sealant without rendering pressurized gas futile, by providing an extraction control valve to an emitting port and allowing said valve to cooperate with the opening and closing valve of pressurized gas through a flexible cable while imparting the control and safe function of gas pressure. CONSTITUTION:When an operation lever 29 is pulled to the direction shown by the arrow against compression springs 25a, 71, a valve lever 27 is slid to the right direction and an opening and closing valve 25 is opened to flow pressurized carbon dioxide into a gas chamber 39 to press the bottom surface of a viscous agent packed cylinder P. At the same time, a flexible cable 73 is pulled to pull down the valve body 61 of an injection control valve 53 and, because a closed elastic pipe 59 is communicated, the viscous agent of the viscous agent packed cylinder P is injected from a nozzle 55. When injection is stopped, the pulling of the operation lever 29 is released. Herein, the gas pressure of the gas chamber 39 is regulated by determining the spring force of the compression spring by rotating a control nut member 103 and a safety valve 41 is operated when said gas pressure reaches or exceeds the predetermined pressure.

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]

BACKGROUND ART Various viscous agent dispensing devices for dispensing viscous materials using pressurized carbon dioxide gas have conventionally existed.

The inventor conducted extensive research to come up with something even better than the conventional one.

[Purpose of the invention]

This invention was made based on such circumstances,
The purpose is to provide a viscous agent dispensing device that does not waste carbon dioxide gas, operates smoothly, is easy to maintain, and is safe.

[Structure of the invention]

And, this purpose is to provide a viscous material filling cylinder having a discharge port,
comprising a gas chamber into which the rear part of the viscous material filling cylinder is inserted, and a pressurized gas source connected to this gas chamber via an on-off valve, and sending pressurized gas from this pressurized gas source to the gas chamber; In the viscous agent dispensing device that pours out the viscous agent from the discharge port by pressing the viscous material filling cylinder, the discharge port is provided with an extraction control valve, and the extraction control valve and the on-off valve are flexible. The flexible cable is connected via a cable, and when the opening/closing valve is opened, the flexible cable is pulled to open the extraction control valve, and an elastic tube for passing the viscous agent is provided in the extraction control valve. The elastic tube is inserted and opened and closed in accordance with the opening and closing of the extraction control valve, and the rear end of the elastic tube is interposed between the extraction control valve and the discharge port of the viscous material filling cylinder, and When inserting the viscous material filling tube into the gas chamber, a sealing member is interposed, and the sealing member is made of an elastic material, has an outer flange at the front end, and has an inner bend integrated with the rear end periphery. The outer flange of the sealing member is inserted between the opening of the gas chamber and the viscous material filling cylinder, and the outer flange is connected to the inner edge of the opening of the gas chamber. The viscous material-filled cylinder is fixed without any gaps, and the rear end peripheral edge of the viscous material-filled cylinder is held between the cylinder body and the inner bent piece, and the gas pressure of the gas supplied to the gas chamber can be adjusted as appropriate, and This was achieved by installing a safety valve that prevents the gas pressure of the pressurized gas supplied to the gas chamber from becoming more than necessary. [Description of Embodiments] The present invention will be described in detail below with reference to FIGS. 1 and 2.

In FIG. 1, 11 is a base of the viscous agent dispensing device, 13 is a gripping tube screwed to this base 11, and 15 is a wire lid that covers the opening of this gripping tube 13.

A carbon dioxide gas cylinder 17 as a pressurized gas source and a pressure reducing means 19 for gradually reducing the pressure of the pressurized carbon dioxide gas flowing out from the carbon dioxide gas cylinder 17 are installed in the grip cylinder 13 (see FIG. 2). Details of these will be described later.

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. 31 is a check valve, which is installed downstream of the on-off valve 25.

Reference numeral 33 denotes an exhaust valve integrally constructed with the check valve 31, and is used to exhaust gas from the gas chamber 39, which will be described later, by pushing a knob 37 against the compression spring 35. In addition, 41
is a safety valve, which is installed above the through hole 23 in the base 11. This safety valve 41 prevents the gas pressure within the through hole 23 from becoming higher than necessary.

Next, 39 is a gas chamber, which is formed at the rear of the base 11. This gas chamber 39 has an opening 42 .
2, the rear part of the viscous agent filling cylinder P is inserted through the sealing member S. The seal member S is made of an elastic material such as rubber,
It consists of a cylindrical body 47 having an outer flange 43 at the front end and an integrated inner bent piece 45 at the curved edge of the rear end. The sealing member S has a cylindrical body 47 that is connected to the gas chamber 39.
The frame member 49 is inserted between the opening 42 of the opening 42 and the viscous agent filling cylinder P, and the outer flange 43 is attached to the inner edge of the opening 42.
By being held between the cylinders 47 and 45, the viscosity agent filling cylinder P is fixed without any gaps, and the rear end peripheral edge of the viscous agent filling cylinder P is held between the cylinder body 47 and the inner bent piece 45.

On the other hand, 51 is a catch having a notch 51a, and the base 1
At the front part of 1, it is adjustable and screwed.

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. Then, the pouring control valve 53 is fixed to the seat 51 in a state in which the viscous agent filling cylinder P is fitted. A valve box 60 is formed between the nozzle 55 of the spout control valve 53 and the fitting 057. 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;
A rack is placed over this window 63. Therefore, this moving pin 6
5 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 pin 65
The elastic tube 59 is inserted between the two. Further, reference numeral 71 denotes a compression spring, which is installed inside the valve box 59 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 in the right direction (arrow direction, FIG. 1) due to the operation of the operating lever 29, the valve body 61 is pulled down against the compression spring 71, and When the lever 29 is released, the valve body 61 is compressed by the compression spring 71.
Because the elastic tube 5 is pushed upward by the elastic repulsion of
9 communication 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.

Next, in FIG. 2, 75 is a cylinder member, which is fixed within the grip tube 13. As shown in FIG. This cylinder member 75 has a partition member 77 screwed into its lower portion. Reference numeral 79 indicates a through hole, which is bored in the partition member 77. This through hole 7
9 allows the spaces on both sides of the partition wall member 77 to communicate with each other.

Reference numeral 81 denotes an unsealing member, which is screwed into the partition member 77. This unsealing member 81 unseals the carbon dioxide gas cylinder 17 at the protruding end.

Further, 83 is a rod, which is loosely inserted into the through hole 79 of the partition member 77. This rod 83 has a valve body 85 at one end and a support body 87 at the other end. The valve body 85 is located inside the unsealing member 81 and closes the through hole 79 by being resiliently repelled by the compression spring 89. On the other hand, the support body 87 is located inside the cylinder member 75, and a piston member 9 to be described later.
It is in pressure contact with 1.

A piston member 91 is fitted above the cylinder member 75 so as to be movable forward and backward. This piston member 91 has a shaft body 95 in which a shaft hole 93 is bored. Further, reference numeral 97 denotes a support member for growing the through hole 99, and the shaft body 95 of the piston member 91 is fitted into the through hole 99 so as to be movable forward and backward, and is installed in a non-rotatable manner. The support member 97 has a threaded portion on its outer periphery, and supports a compression spring 101 (having a stronger spring force than the compression spring 89) that is interposed between the support member 97 and the piston member 91. Reference numeral 103 denotes an adjustment nut member, which is screwed onto the outer periphery of the support member 97. Therefore, when the adjusting member 103 is rotated, the supporting member 97
moves up and down to adjust the strength of the compression spring 101.

In addition, the cylinder member 75, the piston member 91, the partition member 77, the valve rod 83, the support member 97, and the adjustment nut member 103
corresponds to the pressure reducing means in this invention.

Further, since the adjustment member 103 is partially exposed from the grip tube 13, it can be adjusted from the outside of the grip tube 13 (see FIG. 1).

The operation of this pressure reducing means will be explained.

First, the joint NAND member 103 is rotated to determine the spring force of the compression spring 101 passed through the viscous agent. This state (second
When the high-pressure gas in the carbon dioxide gas cylinder 17 is opened in the state shown in the figure, the high-pressure gas passes through the through hole 79 and enters the cylinder member 75, increasing the gas pressure inside the cylinder member 75. When the gas pressure inside the cylinder member 75 becomes higher than the set pressure, the piston member 91 rises against the compression spring 101, so the rod 83 is pressed upward by the compression spring 89 and the valve body 85 penetrates the rod 83. Close hole 79.

As a result, the pressurized gas inside the cylinder member 75 gradually flows out toward the gas chamber 39.

The pressurized gas inside the cylinder member 75 is transferred to the piston member 91.
When the internal gas pressure becomes lower than the set pressure as a result of the gas flowing out through the shaft hole 93, the piston member 91 is lowered by the elasticity of the compression spring 101.

When the piston member 91 descends, the rod 83 is pushed down (the spring force of the compression spring 101 is
9), the valve body 85 lowers and the through hole 7
9 is opened and high pressure gas flows into the cylinder member 75 again.

By repeating this state, the gas chamber 39
can be supplied with pressurized gas that is gradually reduced in pressure and passed through a viscous agent.

[Operation of the embodiment]

When the operating lever 29 is pulled in the direction of the arrow against the compression springs 25a, 71, the valve lever 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 push-pull cable 73 is pulled and the valve body 61 of the pouring control valve 53 is pulled down, and the closed elastic tube 59 is opened, so that the viscous agent in the viscous agent filling cylinder P is poured out from the nozzle 55. It will be done.

To stop dispensing the viscous agent, all you have to do is release the pull on the operating lever 29. Then, the valve body 61 will release the compression spring 7.
Since the elastic tube 59 is pushed upward by the elastic force of the elastic tube 59, the moving pin 65 and the fixed pin 69 cut off the communication between the elastic tubes 59 again. At the same time, the valve rod 27 slides to the right via the push-pull cable 73 to close the on-off valve 25, thereby stopping the supply of pressurized carbon dioxide to the gas chamber 39.
