Description

[Detailed description of the invention] Unexploited 111 is a charging method for injecting filling liquid into a container.
! The present invention relates to a cleaning device, and particularly to a cleaning device that cleans the filling device.

Conventionally, charging devices that include a filling nozzle for injecting filling liquid into a container, a liquid valve for opening and closing a liquid passage for the filling liquid, and a gas passage for discharging air from inside the container have already been widely used. It is well known in use. To clean this type of filling device, usually a cup-shaped member is attached to the tip of the filling nozzle to supply cleaning liquid to the fertilizer liquid passage, and the cleaning liquid is passed from the liquid passage through the cup-shaped member into gas. It is circulated through the aisles to wash various parts.

However, in the case of using such a cleaning means, it is necessary to remove a curve or a tab-shaped member at the tip of each filling nozzle, which makes the work complicated.

Many of the other known cleaning devices also have an attachment corresponding to the cut-shaped member described in 1).
It had the same drawbacks as above.

In view of the above-mentioned drawbacks, the present invention provides a filling device in which a cleaning device is integrated into the filling device so that cleaning can be easily performed without disengaging attachments such as cup-shaped members at the time of cleaning. This provides a cleaning device.

The present invention will be explained below with reference to the illustrated embodiment. In FIG. -1
A filling nozzle 2 is slidably fitted into one part. This filling nozzle 2 consists of a large-diameter cylindrical member 3 that slidably fits into the housing 1, an opening/closing member 5 consisting of a small-diameter oily member inserted into the container 4, and a lower end portion of the opening/closing member 5. 1
1 is sunk into the double outer circumferential position, and
A seal 1'' for electrically sealing the part; and a material 6 are provided.

1- A slind door is formed in the large diameter cylindrical member 3 of the filling nozzle 12 in the axial direction, and it is fixed on the inside side of the housing 1. A support member 8 is inserted into the slit 7, and a vent tube 9 is fixed to the tip thereof, that is, to the shaft portion of the filling nozzle 2. The inside of this vent tube 9 serves as a gas passage 1O. The end protrudes from the center of the housing 1, and the lower end passes through the opening/closing member 5 of the filling nozzle 2 and projects downward.

! - The first cloth of the liquid passage 14 formed in the first shaft part of the housing communicates with the filling liquid tank that stores the filling liquid 1 through a passage (not shown), and the r part communicates with the main liquid that opens and closes this liquid passage 14. Filling through the valve 15 and the slit 7/'
The gap between the handle 2 and the hent tube 9 is communicated.

The above liquid/help 15 has the upper end of the large diameter cylindrical member 3 slidably attached to the outer periphery of the housing 1 and the tube 9, and protrudes from the upper part of the housing 1. A seal is provided between the housing 1 and the large-diameter cylindrical member 3, and between the large-diameter cylindrical members 3 and 1', and between the actuating cylinder member 16 and the HR material 16. When the slint 7 described in 1-2 is positioned on the F side of the sealing member 17, the liquid passage 14 is blocked by the sealing member 17, and the slint door is sealed by the sealing member 17. -1 When placed on one side, the liquid passage 14 can be communicated through the slit 7.

As shown in the enlarged view in Figure 2,
A tr seat member 19 constituting the sub-liquid valve 18 is integrally fixed to the lower end of the trough seat member 19, and the lower end portion of the vent tube 9 is housed in the upper part of the tr seat member 19. -1, and 1. −
1st condition j'Xl! The material 20 is fixed, and this i'51-shaped member 2
The distance between the tube 9 and the tube 9 is set as a fertilizer liquid passage 14. Then, an opening 1-121 is formed in this T5-shaped member 20, and the filling pipe from the
1 to J:y 4 can be filled. 1. The 1 end of the bent tube 9 and the 1) shaped part 4 201 are formed with an opening "1".
It communicates with the outside via 22.

1. Hentoch. - A seal member 27 is provided on the valve seat member 18 at the lower end of the valve 9, and a seal member 27 is provided on the Jr seat.
L'・\": Spring 2 is installed between the single thing 1 and the filling nozzle 2.
8 ri'''; b l-1 Normally, the opening/closing member 5 described in 1 is made into a shield part on the valve seat part old 19 described in I, and the sealing member 27 described in G is attached.
This closes the secondary fluid/elub 18. This situation 18
; Then, close the opening/closing portion 445d between the liquid passage 14 [that is, the opening 1121 of the cylindrical member 20], and the opening 1122 of the cylindrical member 20 (the opening 112 of the cylindrical member 20). , and the main liquid valve 15 is also in a closed state. 1. An annular groove 29 is formed as a communication path on the inner circumferential surface of the opening/closing member 5. The liquid passage 14 and the waste passage 10 can be communicated with each other by 1°.

The actuating cylinder member 16 provided on the outer periphery of the vent tube 9 is biased by a spring 30, and is normally placed at a position where it comes into contact with the supporting member 81z at the end of the l. keeping. (7) - The large diameter cylindrical part 4A3i of the filling/throwing hole 2 is in the state where the oil drain valve 15 is closed fff, and the power level is applied from the oil valve 15 at 1. −

6. The communication hole 31 and the seal member 17 ensure that -
1- Configuring the cleaning valve 32 that opens the liquid distribution passage 14; do.

Further, a kite 135 is provided at the lower part of the housing 1 so as to be freely lowered, and a container guide member 36 is provided at the lower end of the kite rod 35 to guide the ['' section of the container 4 and perform centering.

In the above configuration, normally both the upper liquid/refill valve 15 and the sub-liquid valve 18 are closed, and the opening/closing member 5 of the filling nozzle 2 is closed.
The washing valve 32 is also in a closed state. In this state 18'l, as described in 1-1, the oil passage 14
and the gas passage 10 are in communication via the annular groove 29, or the liquid valve 15 is closed (7X), so that the filling ifV is prevented from flowing into the waste passage 10.

This type of skin, such a container 4 (not shown) IR = H 'ft by the table, the container 4 is rock 'ware guide) ''+1! 1 and 21) The opening of the container 4 is pressed against the sealing member 6 to form a seal. When the container 4 is continued in this state /E), the container 4 is filled. The nozzle 2 is moved against the elastic force of the spring 28, and both liquid valves 15 and 18 are opened. The air in the container 4 passes through the waste passage 10 and is discharged to the column section v1.

When the filling progresses and the liquid level in the container 4 closes the opening 11 of the gas passage 10, does it remain in the container? Since the pressure between p suddenly increases to 1, the injection of the filling + ii liquid to;
When the filling nozzle 2 is lowered from this state, the filling nozzle 2 is raised by the spring 28, and both yt=
7ζ Lube 15. Since +8 is closed, the filling operation becomes Pf.

However, 1. To clean the filling device having the above configuration,
- With both the valves 15 and 18 and the opening/closing member 5 closed, move the operating cylinder member 16 against the spring 30. This opens the cleaning valve 32, so if cleaning liquid is supplied to the liquid passage +4i in this state M, the cleaning liquid flows through the liquid passage 14 and the annular 111!29 and flows into the gas passage IO. Therefore, each part can be cleaned.

In addition, the direction of flow of the cleaning liquid is [-statement and opposite direction 1ii mouth i,
But of course it's a good thing. Further, the liquid valve 15 and the cleaning valve 32 do not necessarily need to be provided separately; for example, the liquid valve 15 may be composed of an electromagnetic if, etc. (T' fl,
If it can be opened and closed at the same time, it can be used for both purposes. Further, the opening/closing member 5 does not need to be operated at all times, but may be turned on during normal filling operation and closed only during cleaning.

As described above, the present invention provides an opening/closing member that opens and closes the opening of the liquid passage and the waste passage into the container, and an opening/closing member that opens and closes the opening of the liquid passage and the waste passage into the container. and a cleaning valve that opens the liquid passage when both openings are closed by the opening/closing member, and when the cleaning valve is opened, the cleaning liquid is distributed between the liquid passage and the gas passage. Since it is designed to allow cleaning, there is no need to remove the attachment of the cup-shaped member when cleaning, and the effect is that the cleaning work can be made easier than before. .
