Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a filling nozzle mounting device used in an automatic filling device for filling containers to be filled with LPG or the like.

A conventional automatic filling device, as shown in Japanese Patent Laid-Open No. 64-40798, places a container to be filled on an electronic scale and connects the gas filling port of a valve attached to the container to be filled. Attach the filling nozzle manually and insert the LP through the filling nozzle.
Start filling with G gas. The filling is completed by automatically closing a filling valve interposed in the LPG gas supply path to the filling nozzle when the weight value of the electronic scale reaches a predetermined value.

Problem to be Solved by the Invention Since the gas filling port of the valve is oriented horizontally, conventionally it has not been possible to automatically determine the orientation of the gas filling port.
The filling nozzle is manually attached to the gas filling port of the valve attached to the container to be filled.

SUMMARY OF THE INVENTION An object of the present invention is to provide a filling nozzle mounting device that can automatically attach and detach a filling nozzle.

Means for Solving the Problems The filling nozzle mounting device of the present invention includes a number of sensing pins that are driven up and down toward a valve mounted on a container to be filled and that are supported so as to be able to move up and down in contact with the valve. A contact part attached to the tip, a position detection part that detects the position of the gas filling port of the valve based on the rising and falling state of the sensing pin, and a contact part that extends toward the gas filling port of the valve at a position specified by the position detection part. The filling nozzle device is characterized by being provided with a filling nozzle device that is driven backward.

According to this configuration, as the contact portion is lowered, the tip of a portion of the sensing pin comes into contact with the valve of the container to be filled and is immediately raised. The position detection section detects the amount by which the sensing pin is pushed up and its position to determine the position of the gas filling port. The filling nozzle device moves the filling nozzle forward and backward based on the determination by the position detection unit and attaches the filling nozzle to the valve.

Practical Example An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

The filling nozzle mounting device of the present invention has a contact portion 3 that is driven up and down toward a valve 2 attached to a container 1 to be filled. The contact part 3 includes a support rod 4 connected to a lifting drive device (not shown), a table 5 attached to the tip of the support rod 4, and a sensing pin pushed into a through hole 6 drilled in the table 5. It consists of 7. The through hole 6 is bored on a circumference having a diameter larger than the diameter of the handle 20 of the valve 2. The sensing pins 7 are all set to the same length. As the support rod 4 is lowered, the tips of some of the sensing pins 7 come into contact with the safety valve 8 of the valve 2 and the circumference of the gas filling port 9, which is formed at a 180° angle with the safety valve 8. When the support rod 4 is further lowered, only the head lO of the sensing pin 7 which is in contact with the circumference of the safety valve 8 and the gas filling port 9 is pushed up from the upper surface of the table 5 as shown in FIG.

Here, the level V2 is the level v between the level vI of the safety valve 8 and the level 2 of the circumference of the gas filling port 9.

The figure shows the case where the position is higher than .

On the outer periphery of the support rod 4 is a cylindrical body with a gear I2 attached.
3 are placed concentrically, and this cylindrical body 13 is driven by a motor 14, which is located on the table 5 and has gears 1
5 and 12. Cylindrical body! A filling nozzle device 17 is attached to 3 via an arm 16. Furthermore, a proximity sensor I8 is attached to the cylindrical body 13 as a position detecting section that detects the position of the gas filling 11 from the rising and falling state of the sensing pin. Here, a proximity sensor 18 is installed to detect the head 10 of the sensing pin 7 that is in contact with the circumference of the gas filling port 9 of the valve 2, and the proximity sensor 18 and the filling nozzle device 2 are installed at different positions. are attached at the same angle around the support rod 4.

When the support rod 4 is lowered to the current position, the motor 14 starts rotating. Sensing pin 7 in contact with the periphery of gas filling port 9
The drive of the motor 14 is stopped at the position shown in FIG. 1 where the proximity sensor 18 detects the head 10 of the person.

At this time, the filling nozzle device 17 is located in front of the gas filling port 9, and the filling nozzle 19 is pushed out from the filling nozzle device 17 in a direction approaching the gas filling port 9 as shown by the imaginary line. is connected to the gas filling port 9.

When filling is completed, the filling nozzle I3 is moved to the filling nozzle device 1.
7 and further raises the support rod 4 to complete one filling operation.

Effects of the Invention As described above, according to the present invention, a large number of sensing pins are attached to the tips of the pins, which are driven up and down toward the valve attached to the container to be filled, and which are supported so as to be able to move up and down in contact with the valve. a position detection unit that detects the position of the gas filling port of the valve based on the rising and falling state of the sensing pin; Since it is equipped with a filling nozzle device,
The position detection unit determines the position of the gas filling port from the position of the sensing pin that has been pushed up by contacting the valve, and the filling nozzle device moves the filling nozzle in and out based on the determination by the position detection unit to close the filling nozzle to the valve. The filling nozzle can be automatically attached to the gas filling port of the gas filling port, saving labor in filling work.
