Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a nozzle length changing tool in a liquid filling machine.
[0002]
[Prior art]
Conventionally, in order to automatically fill liquids such as juice, soft drinks, sake, and soy sauce into a container called a PET bottle, the liquid stored in the liquid tank is filled with a nozzle of a filling machine provided at the bottom of the tank. Through the container.
[0003]
Each container is filled with liquid while discharging air from the container to temporarily close the mouth end of the container with a filling machine at the time of filling. For filling, it is necessary to fill without foaming.
[0004]
Therefore, in order to fill the liquid without forming bubbles in the container, the liquid from the liquid tank needs to be filled along the shoulder of the inner wall of the container, and therefore, with the change of the container or the change of the filling amount, Each time, it is necessary to raise and lower the tank of the filling machine, and it is not possible to perform the switching operation. As a result, the nozzle length of the filling machine can be changed while being attached to the liquid tank. Therefore, the present applicant has developed various devices.
[0005]
[Problems to be solved by the invention]
Therefore, the present invention develops and provides a nozzle length changing tool in a liquid filling machine in which the fine adjustment of the height with respect to the delicate height of a container to be filled with liquid can be easily performed by a simple structure. Is to do.
[0006]
Means for Solving the Invention
The liquid filling machine according to the present invention is provided with holes at several places with a predetermined size on the fixture side so as to be able to cope with a case where a delicate length change is required depending on the container to be filled. In each of the above-mentioned predetermined dimensions and a delicate length, a concave groove ring is bored, and a ball is inserted into each of these holes. Several movable slide rings having a mouth end are provided, and the length of the nozzle is changed by locking.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described with reference to the accompanying drawings. The piston (4) is fitted into the nozzle body (1) via a spring (3), and the fitting (5) for temporarily fixing the nozzle body (1) and the piston (4) at an arbitrary position. ), Wherein holes (6A) and (6B) are formed in the longitudinal direction of the nozzle body (1) and the slidable mounting (5) with a predetermined dimension (α) therebetween. On the other hand, on the outer periphery of the nozzle body (1), at a position corresponding to the height of the container (X) to be filled, the groove groove (7A) is spaced apart from the predetermined dimension (α) + (β) by: A concave groove ring (7B) is provided, and holes (6A) and (6B) of the fixture (5) are respectively provided. A ball (8) is inserted, and two movable slide rings (10) having a tapered mouth end (9) at one end and provided on the outer periphery of the attachment (5) are provided. In the liquid filling machine described above.
[0008]
In addition, the groove ring (7A, 7B, 7C) of the nosul body (1) is provided at three places in the drawing, but if necessary, that is, according to the type of height of the container (X) to be filled. The holes (6A) and (6B) on the side of the fixture (5) are reversely tapered so as to become narrower toward the outside, and the inner ball (8) is attached to the fixture (5). 5) It is configured so that it does not deviate and fall. (11) is an O-ring, and (12) is an air pipe stopper. Furthermore, (13) is a wear ring, (14) is a collar for adjusting the body, (15) is a packing receiver, and (16) is a bottle mouth packing. The arrows in FIGS. 1 and 2 show the flow of the liquid from the liquid tank to the container (X) to be filled.
[0009]
If the height of the container (X) to be filled is slightly different, for example, if the height of the container (X) is changed to a 5 mm higher container or a 5 mm lower container on the contrary, the grooves are arranged side by side in the sense of 5 mm. Although it is impossible to form the ring (7), the interval between the concave groove ring (7A) of the nozzle body (1) and the holes (6A) (6B) on the fixture (5) side, that is, a predetermined dimension If a concave groove ring (7B) is bored at a dimension position obtained by adding (α) plus 5 mm (β), as shown in FIG. 2, a concave groove ring (7B) of the nozzle body (1) is formed. The difference of 5 mm can be easily changed by aligning and locking the hole (6A) of the attachment (5).
[0010]
【The invention's effect】
According to the present invention, even when the height of the container (X) to be filled is slightly different, for example, when the height is different by 5 mm, the piercing position of the concave groove ring (7B) of the nozzle body (1) is changed to the concave. By drilling the space between the groove ring (7A) and the holes (6A) (6B) on the fixture (5) side at a position of a predetermined dimension (α) plus 5 mm (β), it is possible to lock at that dimension. Even when changing to a container (X) having a slightly different height, it is possible to easily cope with the case (X), and to obtain an extremely useful effect.
