As shown in FIG. 10, the packaging and filling nozzle 5 is formed of an elongated passage member having a passage 51 through which the material to be filled passes, and a first locking member is provided on the outside (outside). A part 52 is provided. The first locking portion 52 is, for example, an outwardly projecting member provided outside the tip of the packaging and filling nozzle 5. And the packaging filling nozzle 5
Is raised and lowered by a packaging and filling nozzle lifting and lowering means 6 described below.

The packing / filling nozzle lifting / lowering means 6 raises / lowers the packing / filling nozzle 5. For example, a motor 61 which can be rotated forward and backward, and a male screw 62 which is rotated by the motor 61 are provided.
And a female screw 63 screwed into the male screw 62 and a female screw 63
And a moving support member 64 that moves together with the nozzle and supports the packaging and filling nozzle 5.

A nozzle guide 7 is provided so as to cover the outer periphery of the tip of the packaging and filling nozzle 5. The nozzle guide 7 is formed of a cylindrical body having an open upper end and a lower end. A first locked portion 72 that is locked to the first locking portion 52 is provided on the inner periphery of the cylindrical body, and a second locked portion 72 is provided on the outer periphery. Are provided respectively.

The first locked portion 72 is, for example, as shown in FIG. 10, an inwardly projecting member provided on an inner wall surface separated from the tip of the nozzle guide 7.
The inner wall surface of at least
The first inner wall surface 7a is formed in the order of a convex inner wall surface 7b composed of the convex member of the first locked portion 72, and the first locking portion 52 is formed on the first locked portion 72. In the locked state, the first locking portion
There is provided a gap T (preferably about 1 mm or more) in which the tip 52 and the inner wall surface 7a do not contact each other. The first locked portion 72 is locked to the first locking portion 52 of the packaging filling nozzle 5,
When the packing and filling nozzle 5 is stored so as not to protrude from the tip of the nozzle guide 7, the liquid adhering to the tip of the packing and filling nozzle 5 is prevented from being transmitted to the tip side inner wall surface 7a by the gap T described above. .

The second locking portion 73 locks to the second locked portion 83, for example, as shown in FIG. 10, so as to regulate the movement of the nozzle guide 7. The second locked portion 83
It is a hole provided in the fixed support member 8 fixed at a predetermined position.

Accordingly, the bag-shaped container 3 is supplied in an upside-down state to the mounting member 2 which is rotatably intermittently moved by a vacuum pad (not shown) from the outside, and the mounting member 2 on which the container 3 is mounted is positioned at a predetermined position. When it comes to, as shown in FIGS. 2 and 3,
The filling supply port opening means 4 causes the pads 41, 41 to be adsorbed on the container 3 near the filling supply port 31 to open the filling supply port 31.

With the filling supply port 31 open, the packaging filling nozzle 5 located above the container 3 having the loaded filling supply port 31 is lowered by the packaging filling nozzle elevating means 6. As shown in FIG. 4, the first locking portion 52

In a state where the packaging filling nozzle 5 and the nozzle guide 7 are lowered, when the first locking portion 52 is locked to the first locked portion 72, the packaging filling nozzle 5 is a nozzle. Since the positional relationship is set so as not to protrude from the tip of the guide 7, the tip of the packaging filling nozzle 5 is in a state of being immersed in the nozzle guide 7, and the packaging filling nozzle 5 projects from the tip of the nozzle guide 7. In such a manner, the packaging filling nozzle 5 and the nozzle guide 7 enter the container 3 through the filling supply port 31.

When the lowering of the packing and filling nozzle 5 by the packing and filling nozzle raising / lowering means 6 is continued, as shown in FIG.
The second locking portion 73 is locked to the second locked portion 83, and the movement of the nozzle guide 7 is restricted and stopped. As shown in FIG. 5, only the packaging and filling nozzle 5 is lowered. , Nozzle guide 7
When the packaging filling nozzle 5 reaches a predetermined position, the descent of the packaging filling nozzle 5 stops, and the packaging filling nozzle 5 is inserted into the filling supply port 31 of the container 3. The container 3 is filled with a material to be filled, for example, a liquid.

When filling, the filling material may be filled in a state in which the packaging filling nozzle 5 is stopped. However, when the filling material is a liquid, it is necessary to prevent air from being mixed into the liquid. 6, the packing / filling nozzle 5 may be controlled so as to rise sequentially as shown in FIG. 6 so that the tip of the packaging / filling nozzle 5 keeps an interval of, for example, 1 cm from the liquid surface. When the filling amount of the material to be filled reaches a predetermined value, the filling is stopped, and the packing and filling nozzle 5 is raised by the packing and filling nozzle elevating means 6.

When the nozzle guide 7 rises to a predetermined position, that is, as shown in FIG. 7, when the first locking portion 52 is locked to the first locked portion 72, the packaging filling nozzle 5 and the nozzle guide 7 rises together as shown in FIG.

That is, after filling, the packing / filling nozzle 5 projecting from the tip of the nozzle guide 7 is moved so as not to project from the tip of the nozzle guide 7, and then the packaging / filling nozzle 5 is projected from the tip of the nozzle guide 7. So that the packaging filling nozzle 5 and the nozzle guide 7 are
I move it out of 31.

As described above, when the packaging filling nozzle 5 enters and exits the container 3 through the filling supply port 31, the tip of the packaging filling nozzle 5 does not contact the filling supply port 31.
The material to be filled (for example, liquid) is prevented from adhering to the filling supply port 31 with the nozzle guide 7 interposed therebetween.

The container 3 filled with the material to be filled is moved by the mounting member 2 which is rotatably intermittently moved. In the next step, the supply port 31 for filling is moved to the position shown in FIG. -Toshi-
Will be

Further, in the above-described embodiment, when the packaging filling nozzle 5 and the nozzle guide 7 are put into the container 3 through the filling supply port 31, the packaging filling nozzle 5 and the nozzle guide 7 are simultaneously placed in the container 3. However, the present invention is not limited to this. For example, only the packaging and filling nozzle 5 is placed in the container 3 and then the packaging and filling nozzle 5 projects from the tip of the nozzle guide 7. Then, the packaging and filling nozzle 5 and the nozzle guide 7 may be moved out of the filling supply port 31 in the above-described embodiment. In
However, the present invention is not limited to this.
Only the tip of the nozzle guide 7 may be moved out of the container 3.
