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.

[Process until the invention was completed]

The inventor connects a spout control valve to the discharge port of the viscous agent filling cylinder, rotates the valve body of the spout control valve toward the nozzle by operating an operating lever, and as a result, the spout At the same time, we have filed an application for a viscous agent dispensing device that releases a viscous agent by opening a control valve (patent 19ft +31).

By the way, in this pouring device, since the nozzle is connected to the valve box of the pouring control valve, there is a problem that the direction of the nozzle tends to change when the valve body rotates in the direction of the nozzle.

[Purpose of the invention]

This invention was made based on such a situation, and its purpose is to dispense a viscous agent in which the direction of the nozzle does not change even though the valve body of the dispense control valve is rotated in the direction of the nozzle. The purpose is to provide equipment.

[Structure of the invention]

The purpose of this is to have a filling inserting groove and a seat erected at the tip of this groove, and to remove the viscous agent with a pouring control valve connected to the six discharge ports of the viscous agent filling cylinder. The agent filling cylinder is fitted into the filling insertion groove, and further, a nozzle is connected to the spouting control valve and a rotary valve body is installed, and an operating lever is provided on the valve body, and the operating lever is In the viscous agent dispensing device, the dispensing control valve is operated to press the operating lever toward the nozzle via a power transmission medium to open the dispensing control valve and dispensing the viscous agent. This was achieved by providing a locking piece on the base of the holder and locking the locking piece inside the seat.

[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, which are installed inside the grip cylinder 13. The unsealing mechanism 17 unseals the carbon dioxide gas cylinder 21 housed in the grip tube 13, and the pressure reducing valve 19 gradually reduces the pressure of the pressurized carbon dioxide gas flowing out from the carbon dioxide gas cylinder 21.

23 is a cylindrical valve chamber, and the grip cylinder 13 at the base 11
It is perforated at the top. This valve chamber 23 communicates with a gas chamber 43 described later via a flow path 27 having a check valve 25, and
It communicates with the secondary side of the pressure reducing valve 19 via the communication hole 29 . Reference numeral 31 denotes a valve rod, which is fitted into the valve chamber 23 so as to be movable forward and backward. The valve rod 31 is moved forward and backward by the operation of the operating lever 33, thereby communicating with or blocking the passage 27 and the communication hole 29.

Note that the check valve 25 is integrated with an exhaust valve 35, and is configured to exhaust pressurized gas from the gas chamber 43 by pushing a knob 39 against a compression spring 37.

Next, reference numeral 41 denotes a recessed part for fitting, which is formed in the upper part of the base part 11. This fitting insertion recess 41 is for fitting and inserting the viscous agent filling cylinder P. A gas chamber 43 is formed at the rear of the tube-fitting recess 41. This gas chamber 43
has an opening 43a in the cylinder fitting recess 41111J, and the inner edge of this opening 43a serves as a fitting seat for the viscous agent filling cylinder P. The viscous agent filling cylinder P fits into this fitting seat without any gap, making the gas chamber 43 a sealed space.

On the other hand, 45 is a seat having a notch, and the cylindrical fitting insertion recess 4
1) and is integrally formed with the base 11.

Reference numeral 47 denotes a pouring control valve, which has a nozzle 49 at its tip and a fitting opening 51 integrally formed with a locking collar 47a at its rear end. This spout control valve 47 is screwed to the discharge port of the viscous agent filling cylinder P via its fitting port 51. And the viscous agent filling cylinder P
is fitted, and the locking collar 47a of the fitting opening 51 is engaged with the receiving seat 45. A valve box 53 is formed between the nozzle 49 of the spout control valve 47 and the fitting opening 51. Further, 55 is a circular valve body having a through hole 57, and is rotatably fitted into the inside of the valve box 53.

Reference numeral 59 denotes an operating lever, which is formed integrally with the valve body 55. Therefore, when the operating lever 59 swings, the valve body 5
5 rotates to open and close the pouring control valve 47. In addition, the valve body 5
5 is resiliently repelled by a coil spring (not shown) in a direction that closes the control valve 47, that is, counterclockwise.

Next, 61 is a cylinder filled with hydraulic oil, and is screwed to the base 11. This cylinder 61 has a large diameter portion 61a and a small diameter portion 61b. A small piston 63 is fitted into the small diameter portion 61b of the cylinder 61.

A small piston rod 65 is connected to this small piston 63,
The tip of this small piston rod 65 is in contact with the operating lever 59 of the valve body 55. Also, 67 is a large piston,
It is fitted into the large diameter portion 61a of the cylinder 61. The large piston 67 is connected to the valve rod 31 (corresponding to the large piston rod of the present invention). Further, 69 is a return spring, which is installed in the large diameter portion 61a of the cylinder 61 and returns the valve rod 31 to its original state.

Note that the cylinder 61, large piston 67, and small piston 63 correspond to power transmission means in this invention.

[Operation of the embodiment]

When the operating lever 33 is pulled in the direction of the arrow against the compression spring 69, the valve rod 31 slides to the left. Then, the communication hole 29 and the flow path 27 communicate with each other, and the pressurized carbon dioxide gas flows into the gas chamber 43 and presses the bottom surface of the viscous agent filling cylinder P.

At the same time, the valve rod 31 presses the large piston 67 in the cylinder 61, which in turn advances the small piston and presses the operating lever 59 of the valve body 55 in the spout control valve 47. Then, the valve body 55 rotates clockwise and the through hole 57 becomes approximately horizontal (shape of a virtual line! 3), so the pouring control valve 47 opens.

To stop dispensing the viscous agent, it is sufficient to release the pull on the operating lever 33. Then, the large piston 67 is pushed to the right by the elastic force of the compression spring 69, creating a negative pressure inside the cylinder 61. As a result, the small histone 63 retreats, and the actuating lever 59 of the valve body 55 is moved by the coil spring. It returns to its original state due to its elasticity, and the spout control valve 47 is closed. At the same time, the valve rod 31 slides to the right and opens the communication hole 2.
9 and the flow path 27, the supply of pressurized carbon dioxide gas to the gas chamber 43 is stopped.

〔Effect of the invention〕

The viscous agent dispensing device according to the present invention has a filling insertion groove and a seat provided upright at the tip of this groove, and a dispensing control valve is connected to the discharge port of the viscous agent filling cylinder. In this state, this viscous agent filling cylinder is fitted into the filling insertion groove, and further, a nozzle is connected to the spouting control valve, a rotary valve body is installed, and an operating lever is attached to this valve body. In the viscous agent dispensing device, the viscous agent dispensing device is configured to press the operating lever toward the nozzle via a power transmission medium by operating the operating lever to open the dispensing control valve and pour out the viscous agent. A locking piece is provided at the base of the control valve, and this locking piece is locked inside the catch seat. Therefore, even if the valve body of the spout control valve rotates in the direction of the nozzle, the spout control valve to which the nozzle is connected is difficult to move, so the direction of the nozzle is difficult to change.
