る。2. Description of the Related Art As a filling nozzle device of this type, the one disclosed in FIG. 4 is known. In FIG. 4, the nozzle portion 11A provided at the tip of the filling pipe 11 for filling the fluid into the bag body B has a bag body B held by the holder H with the upper opening B1 opened. It is possible to descend and rise freely in and out of the opening B1. A valve shaft 12 in which a hollow air supply hole 12A is formed is arranged in the filling pipe 11 so as to be movable relative to the filling pipe 11 in the axial direction. A valve body 13 forming a part is attached. In such a filling nozzle device, when the valve shaft 12 descends by a predetermined distance after the nozzle portion 11A enters into the bag body B through the opening portion B1 (the position indicated by the chain double-dashed line in FIG. 4), A gap is formed between the tip of the filling tube 11 and the contents to be filled flow down into the bag B to start filling.

している内容物を吹き飛ばす。When the filling of the contents by a predetermined amount is completed, the valve shaft 12, that is, the valve body 13 is raised to its original position and the nozzle portion 11A is closed. After that, air is blown out from the air supply hole 12A for a short time, and the contents attached to the tip of the nozzle portion 11A are blown off.

記付着内容物が除去されないことが多い。However, in the conventional filling nozzle device shown in FIG. 4, air is blown out from the air supply hole 12A to blow off the contents attached to the tip of the nozzle portion 11A. As is clear from FIG. 4, the tip of the nozzle portion 11A is located on the back side of the valve body 13, and the blown out air does not sufficiently reach and the adhered contents are often not removed.

も、後に腐蝕の問題を生じたり、あるいはかかる問題が
なくとも外観上好ましくない。When the nozzle portion 11A enters and leaves the opening B1 of the bag B while the contents are attached to the tip of the nozzle portion 11A, the inner surface of the opening B1 is contaminated with the contents each time, and the opening is opened. This will cause a sealing failure when sealing the portion B1 later. Further, even if the seal can be formed, a corrosion problem will occur later, or even if there is no such problem, it is not preferable in appearance.

らない。そのために、充填作業の能率が低下する。In order to carry out filling without causing such a problem, the opening is sufficiently widened so that the nozzle portion 11A enters and exits the opening B1 in a low cycle, and air is blown out of the adhered contents at the time of completion of filling. It has to take a long time to remove. Therefore, the efficiency of the filling work is reduced.
【０００７】本発明は、高サイクルで充填を行っても、
袋体の開口部を内容物で汚すことのない充填ノズル装置
を提供することを目的とする。According to the present invention, even if filling is performed at a high cycle,
An object of the present invention is to provide a filling nozzle device that does not stain the opening of the bag with contents.

ことにより達成される。According to the present invention, according to the present invention, the nozzle portion at the tip is relatively movable in the axial direction of the filling pipe into and out of the filling pipe which can freely move in and out of the opening of the bag body. In a filling nozzle device in which a valve shaft is provided, and a valve body that opens and closes an annular gap between the valve shaft and the nozzle part by the movement of the valve shaft is provided at the tip of the valve shaft, at least the tip part is provided. It has a cylindrical nozzle guide that can enter and leave the opening of the bag,
This is achieved by the fact that the nozzle portion is accommodated in the nozzle guide when it enters and leaves the opening of the bag, and projects when it is filled.

なく、該開口部を内容物で汚すことはない。According to the present invention having the above-described structure, when filling is not performed, the nozzle portion closed by the valve body provided at the tip of the valve shaft is lowered and raised while being accommodated in the nozzle guide. Then, it enters into the opening of the bag and is withdrawn.
Therefore, the nozzle portion does not come into contact with the opening portion of the bag body and the opening portion is not contaminated with the contents.

As a preferred form, when the valve shaft is provided with an air supply hole and the nozzle guide is provided with an air supply port, in such a state, air is blown out from the air supply pipe and / or the air supply space, and the contents attached to the tip of the nozzle part Blow away. In particular, since the air flow from the air supply space directly hits the tip of the nozzle portion, the attached contents are effectively removed.
