Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a filling nozzle mounting device used in an automatic filling device for filling LPG or the like into a Wave Light 11 container.

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 start filling with LPG gas through the filling nozzle. 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 valve 1 is oriented horizontally, conventionally it has not been possible to automatically determine the orientation of the gas filling port, and it has been difficult to find the direction of the valve attached to the container to be filled. The filling nozzle is attached to the gas filling port manually.

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 section attached to the tip, a position detection section that detects the position of the gas filling port of the valve from the rising and falling state of the sensing pin, a pulling means for pulling up the sensing pin at a specific position, and a position specified by the position detection section. The present invention is characterized in that a filling nozzle device is provided which is driven to move in and out toward the gas filling port of the valve at the position.

According to this configuration, as the contact portion is lowered, the tips of some of the sensing pins come into contact with the valve of the container to be filled and are pushed up. The position detection section detects the pushed-up claw of the sensing pin and its position to determine the position of the gas filling #11.

When the sensing pin is lowered between the gas filling port of the valve and the filling nozzle of the filling nozzle device, the lifting means pulls up the sensing pin, and then the filling nozzle device responds to the judgment of the position detector. to move the filling nozzle in and out and attach the filling nozzle to the valve.

EXAMPLE Hereinafter, an example of the present invention will be explained based on 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 are located between 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. , and when the support rod 4 is further lowered, only the head IO of the sensing pin 7 that is in contact with the safety valve 8 is pushed up from the soil surface of the table 5, as shown in FIG.

A cylindrical body I to which a gear 12 is attached is attached to the outer periphery of the support rod 4.
3 is covered in the same shape, and this cylindrical body 13 is driven by a gear I5 by a motor I4 installed on the table 5.
and 12. Arm 1 is attached to cylinder 13.
A filling nozzle device 17 is attached via 6.

Furthermore, the cylindrical body I3 is provided with a proximity sensor I8 as a position detection unit that detects the position of the gas filling port from the rising and falling state of the sensing pin.
is installed. Here, a proximity sensor 18 is installed to detect the head lO of the sensing pin 7 that is in contact with the safety valve 8 of the valve 2, and the proximity sensor 18 and the filling nozzle device 2 are installed at the support rod 4. are mounted with a phase difference of 1800 around the periphery.

When the support rod 4 descends to the specified position, the motor 14 starts rotating. Head IO of sensing pin 7 in contact with safety valve 8
The proximity sensor! The drive of the motor 14 is stopped at the position shown in FIG. 1 detected by the motor 8. At this time, the filling nozzle device I7 is located in front of the gas filling port 9, but the sensing pin 7 remains hanging between the filling nozzle 19 of the filling nozzle device 7 and the gas filling port 9. , here, when the filling nozzle 19 is pushed out, the electromagnet 21 attached to the cylinder I3 starts to be energized at the solid line position (3) in Fig. 1, attracts and pulls up the sensing pin 7 located below, and is further attracted. In this state, the electromagnet 21 is driven upward to the virtual line position V4 shown in FIG.
Pull upward from between. After the sensing pin 7 is lifted up by the electromagnet 2I, the filling nozzle 19 is pushed out in a direction approaching the gas filling port 9 as shown by the imaginary line, and the filling nozzle 19 is coupled to the gas filling port 9.

When the filling 1n is completed, the filling nozzle 19 is moved back to the filling nozzle device 17, and the support rod 4 is further raised 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 based on the position of the sensing bottle that is raised by 1111L after contacting the valve, and the filling nozzle device moves the filling nozzle in and out based on the determination of the position detection unit. The filling nozzle can be automatically attached to the gas filling valve (1), which saves labor in filling the valve.

Furthermore, since a pulling means is provided to pull up the sensing bottle at a specific position, even if the sensing bottle hanging between the gas filling port and the filling nozzle hits when the gas filling port is detected by the sensing bottle, Automatic mounting of the filling nozzle can be achieved by actuating the lifting means.
