In a cream filling machine in which a nozzle or a cream container can be raised and lowered by a cam mechanism, the nozzle is divided into a parent nozzle and an adjustment type split nozzle, and the parent nozzle is connected to a nozzle mounting portion of the cream filling machine. A vertical hole that forms a cream passage hole and a receiving hole for the adjustment type split nozzle is formed, and a vertical hole that forms a cream passage hole is formed inside the adjustment type split nozzle, and the upper end of the adjustment type split nozzle. A male screw for attachment to the parent nozzle is formed on the outer periphery in the vicinity, and a stop nut is interposed between the parent nozzle and the adjustment type split nozzle.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a nozzle of a cream filling machine, and more specifically, it stably and quantitatively fills a cream-like or jelly-like high-viscosity liquid, and an air pocket is provided in a container (for example, a semi-artificial glass bottle) with a variable container volume. Nozzle for cream filling machine that fills high-viscosity liquid fully without causing the occurrence of continuous filling work without interruption.

[0002]

[Prior art]

 Conventionally, the filling of a cream as a high-viscosity liquid (hereinafter simply referred to as “cream” or “cream-like”) is generally performed in a container by a metering filling machine equipped with a cylinder and a piston pump.

In this case, it is possible to confirm that a predetermined amount of cream has been filled in the cream container by causing the tip of the filling nozzle of the quantitative filling machine to follow the liquid surface of the cream filled in the container. It was done.

There are two methods for bringing the tip of the filling nozzle closer to the inside of the container: a nozzle elevating type in which the filling nozzle is moved up and down and a container elevating type in which the cream container is moved up and down. In any of the methods, the raising and lowering operation is performed by a known cam mechanism, but the nozzle raising and lowering type is simpler in terms of the structure of mechanical equipment.

[0005]

[Problems to be solved by the device]

 By the way, if there are variations in the container internal volume of the above-mentioned cream container, the following various harmful effects occur.

That is, in the case of a container having a smaller internal volume than the reference internal volume, the outer periphery near the tip of the conventional nozzle B integrally formed as shown in FIG. However, there has been a problem that the conventional container cannot be filled in the next container unless the cream adhered to the nozzle B is wiped off, and consequently continuous filling becomes impossible.

On the other hand, in the case where the internal volume of the container is larger than the reference internal volume, the tip of the integrally formed conventional nozzle B is located away from the surface of the filling cream as shown in FIG. As a result, there was a problem that the filling cream could not be pushed and spread in the container, which resulted in the formation of air pockets in the container where air could accumulate and the cream could not be fully filled.

According to the present invention, the nozzle of the cream filling machine is divided into a parent nozzle and an adjusting type split nozzle, and both are adjustably coupled with a lock nut to eliminate all of the above problems. It is intended to provide machine nozzles.

[0009]

[Means for Solving the Problems]

 Therefore, the present invention is a cream filling machine in which a nozzle or a cream container can be moved up and down by a cam mechanism. In the cream filling machine, the nozzle is divided into a parent nozzle and an adjusting type split nozzle, and the parent nozzle is connected to a nozzle mounting portion of the cream filling machine. A vertical hole that serves as a passage hole for the cream and a receiving hole for the adjusting type split nozzle is formed inside the vertical type hole, and a vertical hole that serves as a cream passing hole is formed inside the adjusting type split nozzle. In the cream filling machine, a male screw for attachment to the parent nozzle is formed on the outer periphery near the upper end of the cast type split nozzle, and a lock nut is interposed between the parent nozzle and the adjust type split nozzle. The nozzle is used as a means for solving the problem.

[0010]

[Action]

 According to the above-described nozzle of the cream filling machine of the present invention, when the locking nut is loosened and the adjusting split nozzle is rotated during the cream filling operation, the adjusting split nozzle is vertically lengthwise steplessly changed. It is possible to adjust, and it becomes possible to freely adjust the entire length of the nozzle simply by tightening the lock nut again after determining the suitable length of the adjusting type split nozzle.

Therefore, as a result, the length of the filling nozzle can be freely adjusted at any time without stopping the cream filling operation.

[0012]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a nozzle of the present invention in an exploded state, and FIG. 2 is a front view of the same in an assembled state. The parent nozzle 1 has a vertical hole 1a formed in a through hole therein.

A vertical hole 2a is also bored inside the adjusting type split nozzle 2 inserted into the vertical hole 1a of the parent nozzle 1, and a male screw 3 is formed on the outer periphery near the upper end of the adjusting type split nozzle 2. Has been done.

The male screw 3 is for screwing into the vertical hole 1 a of the parent nozzle 1 when the adjusting type split nozzle 2 is inserted into the vertical hole 1 a, and adjusts the screwing state. This makes it possible to adjust the length of the protruding portion from the lower end of the parent nozzle in the adjust type split nozzle.

The mounting positional relationship between the parent nozzle 1 and the adjusting type split nozzle 2 is adjusted by loosening or tightening the fastening nut 4.

Next, the filling operation of the cream filling machine using the present invention shown in FIG. 3 will be described. The cream hopper 5 of the cream filling machine A stores the cream, and the parent nozzle 1 receives the cream through the nozzle mounting portion 12. It is attached to the filling machine A.

Further, the male screw 3 at the upper end of the adjusting type split nozzle 2 is screwed into the vertical hole 1 a of the parent nozzle 1. In the figure, reference numeral 6 is a cylinder, and 7 is a piston pump. The cream in the cream hopper 5 is transferred to the filling nozzle by the cylinder 6 and the piston pump 7.

The cream transferred to the filling nozzle is filled into the cream container 8 through the vertical hole 1a of the parent nozzle 1 of the filling nozzle and the vertical hole 2a of the adjusting type split nozzle 2.

At the time of this filling, a nozzle elevating mechanism 11 using a cam 9 and a spring 10 is used to vertically move the entire filling nozzle.

At the time of filling, the protruding size of the adjusting type dividing nozzle 2 is adjusted to be short for a small capacity cream container, and conversely, the protruding size of the adjusting type dividing nozzle 2 is used for a large capacity cream container. Adjust the length to correspond. Before and after the adjustment, the lock nut 4 is loosened and tightened.

[0021]

[Effect of device]

 Therefore, according to the present invention, even a cream container having a large variation in the capacity of the container can be appropriately handled by freely moving the tip position of the filling nozzle up and down during the filling operation. That is, regardless of whether the cream container is smaller than the reference content volume or the cream container is larger than the reference content, it is easy to appropriately adjust the tip position of the filling nozzle.

Further, without changing the design of the nozzle and cam mechanism of the conventional cream filling machine, continuous cream filling work can be performed without interruption, and no air pockets are found in the container filled with cream. Has an excellent effect.
