Description

DETAILED DESCRIPTION OF THE INVENTION (1) The present invention relates to an improvement of a fluid filling nozzle.

(2) Problems to be solved by the invention In a device for filling a container such as a bottle with a fluid, in order to shorten the time required to fill the fluid and improve the work efficiency, in the working process of pouring the fluid into the container Smoothing out the air inside is extremely important. For this reason, a nozzle for injecting a fluid is usually provided with a passage for venting air. However, when the viscosity of the fluid to be filled is low, the fluid flowing into the neck of the container with a strong force spreads temporarily in a part of the neck and becomes a plug,
A so-called "liquid pool" may be formed. The liquid that forms this "puddle" immediately falls due to its own weight, the "puddle" disappears within a very short time, and it is formed again, but even after a short time, the "puddle" Occurs, this prevents the air in the container from reaching the air intake port of the nozzle, and has the effect of countering the shortening of the filling time that obstructed smooth exhaust, and further “liquid pool”.
Since the filling time becomes irregular due to the intermittent occurrence of, the uniformization of the filling amount is also hindered. In order to avoid such a problem, in a nozzle for filling a liquid with low viscosity, the fluid is discharged not from the tip of the nozzle but from the side surface close to the tip, and an air intake port is provided on the opposite side surface. Has been devised.

However, even with such a nozzle,
When the neck of the container is extremely elongated, when the nozzle is inserted, the gap between the nozzle and the inner wall of the container neck is narrow,
It often happens that the fluid exiting the nozzle also forms a "puddle".

That is, referring to FIG. 6, in the conventional nozzle, the inclined plate 2 is provided at the bottom of the fluid outlet 1 facing the side surface so as to inject the fluid laterally. The fluid to be filled in the container hits the inclined plate 2 when flowing out from the nozzle, flows into the container while diffusing into the fan shape 7. At this time, the fluid that has collided with the inner wall of the neck portion of the container is repelled or is transmitted in the circumferential direction of the inner wall of the neck portion and diffused in a wider range. As a result of the fan-shaped diffusion of the fluid in this way, the fluid spreads to the left and right in the gap between the narrow nozzle and the inner wall of the container neck, and when it surrounds the nozzle and is connected on the back side, a "liquid pool" is formed and exhaust is obstructed. To be done.

In a container with a relatively short neck, the above-mentioned problem does not occur because the tip of the nozzle can be inserted under the neck.However, in a container with a long neck, the tip of the nozzle must be the neck because of the structure of the filling machine. The above problem occurs.

It is an object of the present invention to provide a fluid filling nozzle that is relatively simple to improve and that does not create a "puddle" even when used with a container having a significantly elongated neck.

(3) Means for Solving the Problems In the present invention made to achieve the above-mentioned object, an inclined surface which was conventionally formed by one flat surface is extended in the longitudinal direction at a substantially central portion of the inclined surface. It is characterized in that it is composed of two inclined surface portions that form a ridge and intersect each other at a predetermined angle.

(4) Action If the action of the liquid filling nozzle having the above structure is explained with reference to FIGS. 1 to 5, the fluid flowing out from the fluid outlet 1 is at the bottom of the fluid outlet 1 at the vertical ridge 3. The inclined plates 4, 4'which are divided into a mountain shape are divided into two parts, which are then flowed out and flowed into the container. Also in this case, each inclined surface 4,
Although the fluid hitting 4'is a small scale, a pair of left and right fan-shaped 8,
The fluids that form the pair of left and right fan sides 8 and 8'diffuse to the left and right and spread to the left and right, respectively, and become approximately half of the total amount of the fluid, respectively, and the energy that each has becomes small, so that the container Even if it collides with the inner wall of the neck, the momentum of rebounding and spreading will be weak. Furthermore, the forces of the left and right fluids that spread to the left and right in the contacting central portion 5 are canceled and cancelled, so that the force of the flowing fluid as a whole that diffuses to the left and right is greater than that of the nozzle of the conventional structure. Also, the fluid smoothly flows down the neck, and the fluid does not surround the nozzle and connect to the back surface to form a “liquid pool” in a container having a normal diameter.

(5) Examples Hereinafter, examples of the present invention shown in the drawings will be described in detail. FIG. 1 is a side view of a nozzle according to the present invention, FIG. 2 is a front view of the same, FIG. 3 is a longitudinal sectional view of the same, and FIG. 4 is a IV-IV of FIG.
5 is a sectional view taken along line VV of FIG. 2 as well.

A fluid that naturally or under pressure falls from a storage tank (not shown) passes through the fluid passage 6 in the nozzle and flows out from the outlet 1. At that time, the vertical ridges 3 provided at the bottom of the outlet 1 are provided on the left and right sides. It hits the inclined surfaces 4, 4 ′ divided into two and flows down. In this case, the fluid hitting the inclined surfaces 4 and 4'diffuses into a pair of left and right fan-shaped portions 8 and 8'although it is a small scale, the amount of each is approximately half of the total amount, and The energy that it has is small, the momentum that it bounces and diffuses when it collides with the inner wall of the container neck is weak, and the forces that try to spread to the left and right at the contacting central part 5 are canceled and canceled out, and the entire fluid flowing down. As a result, the fluid does not tend to diffuse to the left and right, and the fluid smoothly flows down the neck without forming a “liquid pool”.

With a filling machine that uses 32 nozzles, the capacity is 760 ml.
In the work of filling the long neck bottle with whiskey, when using the conventional nozzle, the average filling time per bottle is 9.28 seconds, and the processing function of one filling machine is 90 bottles per minute. In this case, the ratio of products with insufficient content is 0.16
%Met.

However, when the nozzle according to the present invention is used, the average time required for filling per bottle is 6.58 seconds, the processing capacity of one filling machine is 120 pieces per minute, and the ratio of unsatisfied products is 0.017. %, Clearly improving the work efficiency and making the filling amount of the product uniform.

(6) Effects of the Invention As described above, according to the present invention, as a result of saving the fluid filling time especially for a container having an elongated neck portion, not only the working efficiency is improved, but also the fluid flows smoothly into the container. Therefore, it is effective in making the filling amount uniform.

Further, according to the nozzle of the present invention, not only a container having a wide injection port, but also a container having a shape in which the nozzle must be positioned and filled in a very narrow neck portion, without replacing the nozzle, By using the same nozzle, it is possible to perform filling without causing a liquid pool, and the filling work efficiency is greatly improved.
