Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an apparatus for automatically filling cylinders with liquefied gas or the like.

Prior Art This type of filling device is constructed as shown in FIG. In the filling operation, the cylinder to be filled (container to be filled) is placed on the platform 2 of the platform scale 1, the flexible connecting pipe 4 extending from the filling control section 3 is attached to the valve of the cylinder, and in this state. The filling control unit 3 is configured to flow the liquefied gas as the filling material until the weighed value of the platform scale 1 reaches a specified value. Reference numeral 5 denotes a fence whose lower end is supported by the platform 2 and extends upward along the housing 6 of the filling control section 3, and the fence 5 supports the cylinder on the platform 2.
The placement position of the cylinder is regulated so that the cylinder does not touch the housing 6 when the cylinder is placed on the housing 6.
This prevents the reliability of the weight value from decreasing, which would occur if the weight comes into contact with the weight.

Problems to be Solved by the Invention With such a conventional configuration, there is no problem in the case of a large cylinder A shown by the imaginary line because the position B where the tip of the connecting pipe 4 is connected is located above. In the case of the small cylinder C shown in , there is a problem that the middle part of the connecting pipe 4 comes into contact with the floor surface F, resulting in a decrease in weighing accuracy.

An object of the present invention is to provide a filling device that can fill both large and small cylinders and can control filling with high precision even in the case of small cylinders.

Means for Solving the Problems The filling device of the present invention is connected to a platform scale for weighing a container to be filled and a flexible connecting pipe to the container to be filled, and the weight value of the platform scale becomes a specified value. a filling control unit that allows the filling to flow up to the height of the scale; a fence whose lower end is attached to the platform of the platform scale and extends upward to regulate the placement position of the container to be filled on the platform; and a base end that pivots to the fence. a deployed position that supports a container to be filled that is supported and juts out above the display table and is connected to the connection pipe; and a storage that does not come into contact with the container that is connected to the connection pipe and placed on the display table. The device is characterized by having an opening/closing side whose position can be changed.

Function According to this configuration, the large container to be filled is placed directly on the platform of the platform scale, and the filling material is poured into the container by connecting the connecting pipe to the container to be filled. When filling this large container to be filled, the opening/closing shelf is set in a position where it does not come into contact with the container to be filled. In the case of a small container to be filled, an opening/closing shelf is set at a position that supports the container to be filled, a connecting pipe is connected to the small container placed on the shelf, and the filling material is poured into the container.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Components having the same functions as those in FIG. 3 showing the conventional example will be described with the same reference numerals.

Figure 1 shows a small cylinder C manufactured by the filling device of the present invention.
FIG. 2 shows a state in which preparations are being made for filling a large cylinder A. Reference numeral 7 denotes an open/close shelf composed of a shelf board 8 whose proximal ends are pivoted to the fence 5, and a support arm 9 attached between the tip end of the shelf board 8 and the fence 5. Reference numeral 9 is composed of first and second links 10 and 11 whose ends are connected to each other so that rotation beyond a predetermined angle α is prohibited, and the other end of the first link 10 is connected to a shelf. It is connected to the tip of the plate 8 with a pin 12, and the other end of the second link 11 is connected to the fence 5 with a pin 13.

In this way, when filling a small cylinder C, the shelf board 8 of the opening/closing shelf 7 is pulled up and set so as to protrude above the platform 2, as shown in FIG. A small cylinder C to be filled is placed on top. And valve 1 of this small cylinder C
4 is connected to the connecting pipe 4, and the connecting position of the connecting pipe 4 can be brought to approximately the same upper position D as when filling the large cylinder A. Therefore, even when the small cylinder C is being filled, the middle part of the connecting pipe 4 does not come into contact with the floor surface F. Note that the load of the small cylinder C being filled is transferred to the mounting table 2 via the shelf board 8 and the fence 5.
is loaded and weighed accurately.

When storing the unfolded shelf board 8, with the tip of the shelf board 8 slightly lifted, press the first link 1.
0 and the second link 11 in the direction of arrow E, as shown in FIG. Folded in a position where they do not touch each other. When filling the large cylinder A, place the large cylinder A on the platform 2 with the shelf board 8 folded as shown in FIG.
It is filled by placing it directly.

Effects of the invention As described above, according to the invention, the base end is pivotally supported on the fence attached to the stand of the platform scale for weighing the container to be filled, and extends above the stand to connect the container. An opening/closing shelf is provided whose position can be changed between a deployment position that supports a container to be filled connected to the pipe and a storage position that does not come into contact with the container to be filled that is connected to the connecting pipe and placed on the table. Therefore, if the container to be filled is large, set the opening/closing shelf in a position where it does not come into contact with the container to be filled placed on the platform.
Place the container to be filled directly on the platform and fill it.
In the case of small-sized containers, the container can be placed directly on the platform by setting the opening/closing shelf in a position that extends above the platform and placing the container to be filled on the opening/closing shelf. The connection position of the container to be filled and the connecting pipe can be set at almost the same high position as when connecting the connecting pipe to a large container to be filled, which is placed in the container. Also, the middle part of the connecting pipe does not come into contact with the floor surface, and it can be expected to improve the accuracy of filling small containers.
